A 10 kg mass slides on a frictionless surface with speed 10 m/s, and has an elastic collision with a 2.0 kg mass. Assume both masses remain along a straight line before and after the collision. (a) If the 10 kg mass is at rest after the collision, what was the initial velocity of the 2.0 kg mass? What was the final velocity of the 2.0 kg mass? (b) If the 2.0 kg mass is at rest after the collision,...
Problem 3 (20 points: Two blocks, mA 12.0 kg, mB-5.0 kg slide along a frictionless horizontal surface towards one another as shown below. Assuming the collision is perfectly elastic, determine the velocity of each block after impact, the total amount of kinetic energy the system loses, and the magnitude of the impulse felt by block A during the collision.

Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...
Block A of a mass 0.7 kg is sliding to the right at a speed of 4.7 m/s while block B of mass 4.5kg is sliding to the right with a velocity of 1.2 m/s. The surface is frictionless for both blocks. If they collide perfectly elastically what is the speed of block A after the collision?
