Two buses have equal masses (5,000 kg). Bus A is moving at a velocity of 20 m/s west. Bus B is at rest. When they collide, Bus B bounces off of Bus A. After they collide, Bus A has 0 momentum. What is the final momentum of Bus B? A.) 250 kg m/s west
B.) 105,000 kg m/s west
C.) 0 kg m/s west
D.) 100,000 kg m/s west

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)
