Q1. Consider a 3.0kg ball and a 5.4kg ball in free fall.

What is the net force performing on each?

What is the acceleration of each?

Q2. Two identical cannons fire cannonballs horizontally with the same early velocity. One cannon is located on a platform partway up a tower, and other is on top, four times higher than the first cannon. How much farther from the tower does the cannonball from the higher cannon land than cannonball from the lower cannon?
