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
