In laboratory situations, a projectile's range can be used to determine its speed. To see how this is done, suppose a ball rolls off a horizontal table and lands 1.8m out from the edge of the table.
If the tabletop is 70cm above the floor, determine the time the ball is in the air.
t=0.38s<======answer

Determine the ball's speed as it left the table top.
