## 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).
