1. Two metal balls (A and B) are the same size, but ball A has a mass of 20 kg and ball B has a mass of 10 kg. Ball A is dropped from a height of 100 meters above the Earth in a vacuum (so that we can ignore air resistance). 1 second later Ball B is dropped from the same location. While they both are falling, which has a greater gravitational force acting on it? Explain.

The ball launcher in a pinball machine has a spring of negligible mass that has a force constant of 1.2 N/cm. The surface on which the 100 g ball moves is inclined 10° above the horizontal, and offers a little bit of friction (µk=0.1). The spring is initially compressed by 5 cm. Treat the ball, incline and earth as your system. Use the work energy theorem that is appropriate for the system to find the distance the ball moves up...

QUESTION 3 A girl throws a stone from a bridge. Consider the following ways she might throw the stone. The speed of the stone as it leaves her hand is the same in each case Case A Thrown straight up Case B: Thrown straight down Case C Thrown out at an angle of 45° above horizontal Case D: Thrown straight out horizontally In which case will the speed of the stone be greatest when it...

Each croquet ball in a set has a mass of 0.50 kg. The green ball, traveling at 14.6 m/s, strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionless surface and all collisions are head-on, find the final speed of the blue ball in each of the following situations: a) The green ball stops moving after it strikes the blue ball. Answer in units of m/s. b) The green ball continues moving after the...
