A projectile is fired at 30°. Neglecting friction, the change in kinetic energy when it returns to the ground will be
Options
(a) zero
(b) 30%
(c) 60%
(d) 100%
Correct Answer:
zero
Explanation:
In case of projectile motion,
K.E. at projection = K.E. at landing on ground.
Hence there is no change in K.E.
