Two balls traveling in opposite directions collide head on. Ball1 is traveling in the positive x direction at a speed of v1 = 4.50 m/s and mass of m1 = 2.0 Kg. Ball2 is traveling in the negative x direction at a speed of v2 = -6.50 m/s and a mass of m2 = 4.0 Kg.

a) If we assume that the two balls are made of clay and become one mass during the collision what is their combined final velocity? (Think conservation of momentum and be careful of your signs)

b) If we assume that they are made of steel and do not become one mass and the collision can be treated as anelastic collision what is the final velocity of Ball1. (Be careful of your signs here too)

c) Consider Ball1’s change in momentum during the collision and calculate the impulse that it feels as a result of the impact.

d) If the contact takes place over Δt = 0.03 seconds what is the force exerted on Ball

Two cars approach an ice-covered intersection. One car, of mass 1.21 X 10^3 kg, is initially traveling north at 12.1 m/s. The other car, of mass 1.62 X 10^3 kg, is initially traveling east at 12.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. magnitude: ______ direction: _____ north of east

When a cue ball strikes the 8-ball, we can assume that the collision is elastic. An 8-ball has a mass of 0.160 kg, and we have made a special cue ball, with a lead core, to have a mass that is 3 times as much as the 8-ball's mass, or 0.480 kg. Let's say this heavy cue ball, initally moving at 1.5 m/s, strikes the 8-ball, and the 8-ball's subsequent velocity is in the same direction as the initial velocity...
