A ball is projected with an velocity`V_(0)` at an angle of elevation `30^(@)`. Mark of the correct statement.

A

Kinetic energy will be zero at the highest point of the trajectory

B

Vertical component of momentum will be conserved

C

Horizontal component of momentum will be conserved

D

Gravitational potential energy will be minimum at the highest point of the trajectory

Text Solution

Verified by Experts

The correct Answer is:
C
Since, horizontal component of velocity is constant.
