A 1000 kg block is pushed over flat ground, speeding up at 2 meters per second squared. In front of it is a 100 kg block, which is pushed along by the 1000 kg block. The index of kinetic friction between the blocks and the ground is .4.

a) What is the net force on the 100 kg block?

b) What is the magnitude of the normal force the 100 kg block exerts on the 1000 kg block?
