At the highest point of the path of a projectile, its

A

speed is zero

B

spoeed is minimum

C

kinetic energy is minimum

D

Potential energy is maximum

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
At the highest point of the path the particle has only horizontal component of velocity which is constant hence speed is minimum. Also at the highest point potential energy is maximum, so the kinetic energy will be minimum.
