Question: 1. A marble moving 1.3-m/s rolls off the top edge of a 135.3-cm high table in a room where there is no appreciable air resistance and the acceleration due to gravity is 9.80 m/s
2. How far from the base of the table in cm will it strike the floor?
3. What is the maximum range that a 'lob-ster' can fire a tennis ball in meters if the ball is fired at 41.4-m/s?
