A 2.0-g particle moving at 7.2 m/s makes a perfectly elastic head-on collision with a resting 1.0-g object.

(a) Find the speed of each particle after the collision.

2.0 g particle     m/s
1.0 g particle     m/s


(b) Find the speed of each particle after the collision if the stationary particle has a mass of 10 g.

2.0 g particle     m/s
10.0 g particle     m/s


(c) Find the final kinetic energy of the incident 2.0-g particle in the situations described in parts (a) and (b).

KE in part (a)     J
KE in part (b)     J


In which case does the incident particle lose more kinetic energy?

A heavy 3.8 kg block moves at 4.2 m/s and then makes a head-on elastic collision with a lighter, stationary block of mass 1.7 kg. Use conservation of momentum and the fact that the relative speed of recession equals the relative speed of approach to find velocity of each block after the collision. Check your answer by calculating the initial and final kinetic energies of each block. Show work and explain

A 200-g particle moving at 5.0 m/s on a frictionless horizontal surface collides with a 300-g particle initially at rest. After the collision the 300-g object has a velocity of 2.0 m/s at 45o below the direction of motion of the incoming particle. What is the velocity of the incoming particle after the collision? What percentage of the initial kinetic energy is lost in the collision?
