A projectile is fired at 30 o with momentum p. Neglecting friction, the change in kinetic energy when it returns to the ground will be
Text Solution
Verified by ExpertsThe correct answer is:
A
The energy possessed by a body due to velocity 
is known as kinetic energy of the body.
When a body is projected with velocity v at an angle 
with the horizontal, then kinetic energy (KE) of projection
kinetic energy of returning.
Since, velocity of projection is equal to velocity of return.
Hence, change in kinetic energy is zero.
