Q1. A ball of mass 60 g is dropped from a height of
3.4 m. It lands on the top of a frictionless ramp at height 1.8 m.
The ramp is tilted at an angle of 20 degrees.
(a) What is the velocity of the ball at the top of the
ramp?
(b) At the bottom of the ramp it collides with and
sticks to a ball of mass 73 g. What is their velocity after the
collision?
(c) The stuck together balls collide with a spring of
spring constant 300 N/m. How much will they compress it?
(d) They then go back up the ramp. How high will they
go?

A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?

Ball 1, with a mass of 139 g and traveling at 13.6 m/s , collides head on with ball 2, which has a mass of 349 g and is initially at rest. Assume that ball 1 is traveling to the right before the collision and that the collision is one dimensional. Part A What is the final velocity of ball 1 if the collision is perfectly elastic? Part B What is the final velocity of ball 2 if the collision...
