Problems
Problem 1.1:
Two balls with equal masses, m, and equal speed, v, engage in a head on
elastic collision. What is the final velocity of each ball, in terms of m and
v?
[Solution]
Problem 1.2:
Two balls, each with mass 2 kg, and velocities of 2 m/s and 3 m/s collide head
on. Their final velocities are 2 m/s and 1 m/s, respectively. Is this collision
elastic or inelastic?
[Solution]
Problem 1.3:
Two balls of mass m1 and m2, with velocities v1 and v2 collide head
on. Is there any way for both balls to have zero velocity after the collision?
If so, find the conditions under which this can occur.
[Solution]
Problem 1.4:
A car of 500 kg, traveling at 30 m/s rear ends another car of 600 kg, traveling
at 20 m/s. in the same direction The collision is great enough that the two cars
stick together after they collide. How fast will both cars be going after the
collision?
[Solution]
Problem 1.5:
One pool ball traveling with a velocity of 5 m/s hits another ball of the same
mass, which is stationary. The collision is head on and elastic. Find the final
velocities of both balls.
[Solution]
