Let V be the velocity with which the ball is thrown, then the kinetic energy E= 1/2*m*V^2. The horizontal and vertical components of velocity, Vx = Vcosx, Vy = Vsinx, will be V/sqrt(2) as the angle of inclination, x is 45 degrees.
Accordingly, What will be the kinetic energy of a body when it reaches at its maximum height?
The thrown body consists of kinetic energy but on reaching the maximum height, all the kinetic energy of the body gets converted to the potential energy of the body. So at the maximum height, the kinetic energy of the body will be zero.
next, How does the angle affect kinetic energy?
If changing the angle of the incline doesn’t affect the height of the plane, then the velocity at the bottom will not change because there is still the same potential energy at the top which is totally converted to kinetic energy at the bottom based on the Law of Conservation of Energy and this only applies to a …
In this manner, Does angle matter for kinetic energy? If a body is projected with the same initial velocity in every case then of course it has the same initial kinetic energy in every case regardless of the angle of projection. Now, the maximum height or the height gained by the body in a projectile is dependent on the angle with which it is projected.
What is the kinetic energy of a 150 kg object?
Kinetic Energy=1/2×m×v^2,Where m=mass,v=velocity. So, kinetic energy of the object=1/2×150×15^2 = 16875 kg m^2 s^-2 . Kg m^2 s^-2 = Joule ,so The kinetic energy of a body of mass 150 Kg moving at 15m/s is 16875 Joules.

What is the acceleration at maximum height?
At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.
What is the kinetic energy just before it hits the ground?
Right before it hits the ground, the initial potential energy and the final kinetic energy will equal each other due to conservation of energy. If we solve for initial potential, we can find final kinetic energy.
Does steepness affect kinetic energy?
The kinetic energies are different, and the block on slope 1 has greater kinetic energy. Slope 1 is steeper, so the block gets to the bottom faster. Therefore it has a greater kinetic energy at the bottom.
What is the impact of kinetic energy?
Kinetic energy is the energy of motion. Kinetic energy can also transform back into potential energy. For example, you’d use kinetic energy to lift a ball to the top of a ramp. That energy would be stored in the ball as potential energy.
Does work depend on angle?
The angle between the force and displacement : Work is directly proportional to cosine the angle between the force and the displacement at constant force and constant displacement .
At what angle is the most work done?
The maximum work is done when the force, F, has an angle of 0 or 180 degrees with the displacement. This means that for any angle between 90+ and 180 degrees, the work done is negative, which means that the force is taking energy away from the moving object.
What is the kinetic energy of a 150 kg object that is moving with a speed of 15 m/s Brainly?
ANSWER: Kinetic energy is 1125 J.
What is meant by kinetic energy?
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. … Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
What is the kinetic energy of a 150 kg object that is moving with a speed of 15 m/s required to answer single line text?
The answer is 16875J.
Why is acceleration zero at maximum height?
Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
At what part of a path does a projectile?
Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning of the trajectory, after which the only interference is from gravity.
When the bullet reaches its maximum height Its acceleration is zero?
When a projectile reaches maximum height, the vertical component of its velocity is momentarily zero (vy = 0 m/s). However, the horizontal component of its velocity is not zero.
What is the kinetic energy of a ball hitting the ground?
As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of an object is the energy it possesses due to its motion. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface.
How do you find the kinetic energy of a falling object?
When the object is dropped, thrown downward or projected upward, its kinetic energy becomes KE = mv2/2, along with a factor of the initial velocity. The sum of the PE and KE is the total energy (TE), which is a constant.
What happens to kinetic energy when an object hits the ground?
When an object falls freely, its potential energy gets converted into kinetic energy. When the object hits the ground, its kinetic energy gets converted into heat energy and sound energy.
How does size affect kinetic energy?
In fact, kinetic energy is directly proportional to mass: if you double the mass, then you double the kinetic energy. Second, the faster something is moving, the greater the force it is capable of exerting and the greater energy it possesses. … Thus a modest increase in speed can cause a large increase in kinetic energy.
What is the kinetic energy of the block?
The total energy of the system of a block and a spring is equal to the sum of the potential energy stored in the spring plus the kinetic energy of the block and is proportional to the square of the amplitude ETotal=(1/2)kA2. E Total = ( 1 / 2 ) k A 2 . The total energy of the system is constant.
Does speed affect kinetic energy?
It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.
Does kinetic energy increase with height?
Contrary to potential energy, the kinetic energy of an object is relative to other stationary and moving objects present in its immediate environment. For instance, the kinetic energy of the object will be higher if the object is placed at a greater height.
What is the kinetic energy of an object?
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
