Compute all parts of given question:
Question: 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 1.5m out from the edge of the table.
Part A: If the tabletop is 85cm above the floor, determine the time the ball is in the air?
Part B: Determine the ball's speed as it left the table top?
I need help to find the time the ball is in the air.
