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. |

Answer» Solution :(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 stationaryKE is same in both FRAMES. |
