a)In outer space, far from other objects, block 1 of mass 61 kg is at position <14, 14, 0> m, and block 2 of mass 1600 kg is located at position <16, 14, 0> m. What is the (vector) gravitational force acting on block 2 due to block 1? It helps to make a sketch of the situation.
(b) At 4.1 seconds after noon both blocks were at rest at the positions given above. At 4.6 seconds after noon, what is the (vector) momentum of block 2?
(c) At 4.6 seconds after noon, what is the (vector) momentum of block 1?
(d) At 4.6 seconds after noon, which one of the following statements is true? Block 2 is moving faster than block 1. Block 1 and block 2 have the same speed.

Block A in (Figure 1) has mass 1.00 kg, and block
B has mass 3.00 kg. The blocks are forced together,
compressing a spring S between them; then the system is
released from rest on a level, frictionless surface. The spring,
which has negligible mass, is not fastened to either block and
drops to the surface after it has expanded. The spring has force
constant 711 N/m and is initially compressed 0.225 m from its
original length.
