✩ A B I The finger pushes two blocks along the bench. The mass of A is 3 kg and the mass of B is 2 kg. The blocks start from rest. Suppose there is no friction. second. At the end of this time the blocks are moving at 2 meters per second. The finger pushes with constant force for one 1. How much force must the finger exert on block A? 2. How much force must block A exert on block B and in which direction? 3. How much force must block B exert on block A and in which direction? Which physics law leads you to this conclusion? 4. Initially, the lower left comer of block A is at the origin x = 0. Draw a graph of the position of the lower left corner of block A as a function of time for times between t=0s and t = 1 s. 1.0 m .8 m .6 m 4 m 2 m .8 s 5.
