11. Block A and block B move toward each other on a level frictionless track. Block A has mass m and
velocity +v. Block B has mass 2m and velocity -v. The blocks collide, and during the collision the
magnitude of the net force exerted on block A is F. What is the magnitude of the net force exerted
on block B, and why does it have that value?
a) 2F, because the mass of block B is twice that of block A and the blocks have
the same acceleration during the collision.
b) F/2, because the mass of block B is twice that of block A and the blocks have
the same acceleration during the collision.
c) F, because the blocks have the same speed immediately before the collision.
d) F, because the net force is equal to the mutual contact force between the
blocks.
