Blocks A (mass 3.50 kg ) and B (mass 7.00 kg ) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 5.00 m/s . The blocks are equipped with ideal spring bumpers. The collision is head-on, so all motion before and after the collision is along a straight line. Let +x be the direction of the initial motion of block A.

Part A Find the maximum energy stored in the spring bumpers.

Part B Find the velocity of block A when the energy stored in the spring bumpers is maximum.

Part C Find the velocity of block B when the energy stored in the spring bumpers is maximum.

Part D Find the velocity of block A after they have moved apart.

Part E Find the velocity of B after they have moved apart.

    4. Two blocks with masses 10.0 kg and 15.0 kg are placed on a horizontal frictionless surface. A light spring is placed in a horizontal position between the blocks. The blocks are pushed together, compressing the spring, and then release from rest. After blocks have lost contact with the spring, the 10.0 kg mass has velocity, v = 4.0 î m/s. (a) How much potential energy was stored in the spring before the blocks were released? (b) What is the...

    Block 1 (mass 2.00 kg) is moving rightward at 10.0 m/s and block 2 (mass 5.00 kg) is moving rightward at 3.00 m/s. The surface is frictionless, and a spring with a spring constant of 1120 N/m is fixed to block 2. When the blocks collide, the compression of the spring is maximum at the instant the blocks have the same velocity. (a) Find the maximum compression. (b) Find the final velocities of the two blocks.

    Block A of mass 2.00 kg and block B of mass 3.00 kg slide on a frictionless surface toward one another and collide. Before the collision, block A moves east with a speed of 3.00 m/s, block B moves south with a speed of 1.50 m/s. After the collision, block A moves 12 degrees west of south with a speed of 0.500 m/s. The two blocks do NOT stick together after the collision. (a) What is the magnitude and direction...
