# Cannon ball!

Friends Stella and Robert each have a ball of the same size, except Stella's ball is made of steel, while Robert's is rubber. They are having a competition to see who can launch their ball farthest. If they each have a cannon capable of accelerating their ball to $50\text{ m/s}$ at the same angle of projection, who will win?

Details and Assumptions:

• The balls are shot through the air, but no wind is blowing.
• The distance is measured from the cannon to the point at which the ball first hits the ground.
