Sorry if this is a stupid question, but do you mean write different force equations for A and B?
So for A it would be F=10kg X 10m/s2=100N
and for B it would be F=2kg X 10m/s2 = 20N
Homework Statement
Two blocks are pushed to the right so that they move together with increasing speed. Block B remains at the height shown. Ignore friction between the ground and block A but not between block A and block B. The mass of block A is 10kg and the mass of block B is 2kg. Let...
