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 a force constant 711 N/m and is initially
compressed 0.225 m from its original length. a) What is the
acceleration of block A just after the blocks are released? b)What
is the acceleration of block B just after the blocks are released.
c)What is the final speed of block A after the blocks leave the
spring? d) What is the final speed of block B after the blocks
leave the spring?
