projectile motion

Question

A projectile on its path gets divide into two pieces at its highest point what is true?

a-Momentum increases

b-Momentum decreases

c-Kinetic energy increases

d-Kinetic energy decreases

Answer 1

Option (c) is correct.

Explanation:

The two pieces fly in opposite directions in accordance with the law of conservation of momentum. The energy of explosion will add to the kinetic energy.

Hence, the Kinetic energy will increase.

Answer 2

At highest point,if the particle gets converted into 2 parts then it's potential energy is converted into Kinetic energy of particles.

So,Kinetic energy increases.
