Here is the situation. Mass 1 rolls over the surface with no friction but mass 2 does slide with friction. Mass 1 is 3 kg. Mass 2 has a coefficient of kinetic friction is 0.30 with the surface. Mass 3 is 4 kg. When released from rest, mass 3 falls 9 meter in 3 seconds. Use g = 10 m/s/s.

1. How many Newton's second law equations can you write for this problem?

2. How many forces are on mass 1?

3. What is the mass of mass 2?

4. What is the normal force between masses 1 and 2?
