Two blocks A and B have different kinetic energies \(K_{A} \text { and } K_{B}\left[K_{B}>K_{A}\right]\). Both are released on a rough horizontal ground. If the coefficient of friction is same for both the blocks, then
- more work has to be done by friction to stop block B
- B will travel more distance before coming to rest
- momentum of B is greater than momentum of A
- given data is insufficient to determine any things
Answer
(A) more work has to be done by friction to stop block B
