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.
15) After time, t, which block has more momentum?
The block of mass M
The block of mass 2M
They will have the same momentum
16) After time, t, which block has more kinetic energy?
The block of mass M
The block of mass 2M
They will have the same kinetic energy
17) After time, t, which block is moving the fastest?
The block of mass M
The block of mass 2M
They will have the same speed
Explanation / Answer
15) Both have the same momentum.
16) The block of mass M.
17) The block of mass M.
