Question

A marble of mass 'm' is dropped from a height 'h' on a hard floor. If it rebounds to the same height, the
change in momentum of marble is
​

Answer 1

Answer:

2Mv or 2 times the intial momentum

Explanation:

change in momentum = final p - intial p

Intial p = mv

final p = -mv ( as momentum is a vector quantity ) and here it's direction has reversed that's why i took negative

hence change is P = 2mv
