Q1. Two 275 kg (611 lb) masses are separated by a distance of 10 m. Using Newton's law of gravitation, find out the magnitude of the gravitational force exerted by one mass on the other.

Q2. A superball and a clay ball are dropped from a height of 10cm above a table top. They have the same mass 0.05kg and the same size. The superball bounces off the table and rises back to the same height. The clay ball sticks to the table. For the superball in the previous question, if it was in contact with the table for 37ms, compute the average force exerted on the ball by the table.

First work out the momentum before and after hitting the table. Don't forget the gravitational force.
