Question

What is the ratio of p e with respect to ground and k e at the top of most point of the projectile motion?

Answer 1

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.

Answer 2

Explanation:

At the ground level the potential energy is zero because the height is Zero .

At the top most Kinetic energy is zero because the velocity of particles is zero at that point
