What is the kinetic energy of the ball when it is at its maximum height?

What is the kinetic energy of the ball when it is at its maximum height?

zero/
At an object’s maximum height, kinetic energy is zero/ maximum while the potential energy is zero/ maximum.

How do you find kinetic energy of an angle?

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.

What is the kinetic energy of a 0.135 kg baseball thrown at 40.0 m s?

Ek=(0.135)(40.0)22 . Ek=108J .

What is the kinetic energy of a projectile at its maximum height?

The vertical velocity of a projectile is zero at its maximum height, so vertically , the projectile will have no kinetic energy. This is because all the energy will have become potential energy at that point.

Why is the kinetic energy zero at the top most point?

Thus at the top most point the kinetic energy becomes zero as “Ke=1/2mv²” and v(velocity) is zero here. Instead entire kinetic energy changes to potential energy. 2. If a projectile is projected at some angle to the horizontal then the velocity wouldn’t be zero at the top most point.

Where does kinetic energy come from at the maximum altitude?

Kinetic energy comes from movement. At maximum height the projectile has stopped and is about to start falling. No movement, no KE. Edit: As Cameron mentioned in his answer, there would still be KE at the maximum altitude if the projectile was not fired straight up.

Is the velocity of a projectile zero at the top most point?

It depends upon whether the projectile is vertically upwards or at an angle with horizontal. 1: If body is moving vertically upward then it would definitely be zero at the top most point since there is only vertical velocity applied to the body (in Y direction).
