Consider two masses sliding across a frictionless surface about to undergo a head-on collision as shown in the figure. The first mass (m1 =3 kg) is travelling to the right with a speed of v1 = 8 m/s. The speed of the second mass (m2 = 5 kg) is unknown. After the masses collide, ma rebounds moving off at a speed of v = 2 m/s in the opposite direction, while mz is motionless. a)(10 pts.)

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...
