A projectile is projected with a kinetic energy K. Its range is R. It will have the minimum kinetic energy after covering the distance equal to :

A

0.25R

B

0.5R

C

0.75R

D

R

Text Solution

Verified by Experts

The correct Answer is:
B
After covering distance `R/2` , the projectile is at max height where vertical velocity is zero and hence K.E. is minimum.
