Blocks A and B are initially at rest on a horizontal frictionless surface with a spring of negligible mass compressed between them. Block A has mass 5.0 kg and block B has mass 20.0 kg. The spring is released and the blocks move off in opposite directions. After the blocks, have moved away from the spring. A) the magnitude of the momentum of block A is the same as the magnitude of the momentum of block B  B) the magnitude of the momentum of block A is less than the magnitude of the momentum of block B  C) the magnitude of the momentum of block A is greater than the magnitude of the momentum of block B
Two blocks are at rest on a horizontal frictionless surface with a compressed spring of negligible mass between them. Block A has mass 2.00 kg and block B has mass 5.00 kg. The blocks are released from rest and move off in opposite directions, leaving the spring behind. If block B has speed 0.800 m/s after it leaves the spring, what is the speed of block A after it leaves the spring? (Block A is the less massive block.) (a) 0.63 m/s (b) 0.95 m/s (c) 1.00 m/s (d) 1.26 m/s (e) 1.50 m/s (f) 2.00 m/s (g) none of the above answers
Margie (of mass 41 kg) and Bill (of mass 65 kg), both with brand new roller blades, are at rest facing each other in the parking lot. They push off each other and move in opposite directions, with Margie moving at a constant speed of 18 ft/s. At what speed is Bill moving? 1. 12.5735 2. 8.4 3. 9.0 4. 13.871 5. 7.61905 6. 8.65574 7. 11.9118 8. 11.3538 9. 10.2857 10. 9.53333
Adam ( mA = 80 Kg) and Barbara (mB = 60 Kg) are initially together at rest on an ice rink. When they push each other part, Adam moves with velocity vA = (3  m/s)î - (9  m/s)jˆ. Assuming that there is no friction from the ice, what is Adam’s velocity?

Boxes A and B are at rest on a horizontal frictionless surface with a compressed spring of negligible mass between them. Box a has mass 2.0 kg and box B has 4.0 kg. When the spring is released the two boxes move off in opposite direction and the spring is left behind. After the boxes have moved away from the spring,A) the magnitude of the momentum of A is less than the magnitude of the momentum of BB) the magnitude of the momentum of A is greater than the magnitude of the momentum of BC)  the magnitude of the momentum of A is equals than the magnitude of the momentum of BD) the kinetic energy of A equals the kinetic energy of B
A man whose mass is 85 kg and a woman whose mass is 50 kg sit at opposite ends of a canoe 5 m long, whose mass is 45 kg. Assume the man is seated at x = 0 and the boat extends along the positive x axis with the woman at the other end. Suppose that the man moves quickly to the center of the canoe and sits down there, while the woman moves quickly 1/3 the length of the canoe towards the man. How far does the canoe move in the water? Assume force of friction between water and the canoe is negligible. 1. 0.972222 2. 0.864865 3. 0.72 4. 1.18056 5. 0.903226 6. 3.29 7. 1.59375 8. 1.13636 9. 0.944444 10. 1.35484
