A man in an open car moving with high speed, throws a ball his full capacity along the direction of the motion of the car . Now the same man throws the same ball when the car is not moving. In which case the ball possesses more kinetic energy in
(a) ground frame
(b) car frame.

Text Solution

Verified by Experts

(a) `KE=1/2m(c)+v_(p)^(2)`
(b) `KE=1/2m(v_(p))^(2)`, Where `v_(c)=v_("car"),v_(p)=v_("particle")`,
In the ground frame the ball possess more Kinetic energy
In second case, since the car is stationary KE is same in both frames.
