A 2 kg ball is moving at 3 m/s to the right and hits a 3 kg ball moving to the left at 4 m/s. After the collision the two balls stick together. All this is happening on a level frictionless surface. Questions 28-31 refer to this situation. In this collision: Momentum is not conserved, KE is not conserved Momentum is conserved, KE is not conserved Momentum is conserved, KE is conserved Momentum is not conserved, KE is conserved

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. Block B acquires a speed of 1.50 m/s. Figure 1 of 1 Part A What is the final speed of block A ? Express your answer in meters per second. Submit Request Answer Part B How much potential energy was stored in the compressed spring? Express your answer in joules.Block A in (Figure 1) has mass 1.00 kg, and block B has mass 3.00 kg.
