Two blocks, of masses m and M, lie in contact on a horizontal surface. The contact surfaces of each block are coated with an explosive. Upon detonation, this explosive releases a fixed amount of energy E. Assuming all this chemical PE is converted to the mechanical KE of the blocks, calculate the speed u of the block m, and the speed v of the block M immediately after detonation. Give numerical values for u and v if m = 6kg, M = 10kg, and E = 5160J (this is the energy which would be released by about 1.24g of TNT).

Two blocks with masses 3.0 kg and 5.0 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 released from rest. After contact with the spring ends, the 5.0-kg mass has a speed of 2.0 m/s. How much potential energy was stored in the spring when the blocks were released?

Two blocks are held together, with a compressed spring between them, on a horizontal frictionless surface. When the system is released, the spring pushes the blocks apart and they then move off in opposite directions. The spring remains behind, and you can assume that all of its energy is transformed to the kinetic energy of the blocks.

A block with mass m is undergoing SHM on a horizontal, frictionless surface while attached to a light, horizontal spring that has force constant k. You use motion sensor equipment to measure the maximum speed of the block during its oscillations. You repeat the measurement for the same spring and blocks of different masses while keeping the amplitude A at a constant value of 18.0 cm. You plot your data as v2max versus 1/m and find that the data lie...
