Question

The same constant force, F, is applied to two blocks. The first block has a mass of M and the second block has a mass of 2M. Both blocks are initially at rest and the force acts on each of them for the same period of time, t.

After time, t, which block has more momentum?A. The block of mass MB. The block of mass 2MC. They will have the same momentum

Answer 1

Answer:

C. They will have the same momentum

Explanation:

Force F acts on each of mass M and 2M for a time period of t ,

Impulse created on each = F x t

Impulse = change in momentum .

Initial momentum of each = 0

Increase in momentum is same for both  as impulse created on them is same. So final momentum of each will be same.
