Homework Help: Physics

Posted by Brandy on Tuesday, November 16, 2010 at 8:15pm.

A 1.5 kg
basketball is thrown to the floor. At the moment it first hits the floor, the basketball has a
velocity of 6 m/s directed 45 below the horizontal. In contact with the ball for 0.1 seconds, the
floor exerts upon the ball a force of 135 N directed 110 above the horizontal. What is the
velocity (magnitude and direction) of the ball at the moment it leaves the floor?
Once the ball leaves the floor, it is in projectile motion. How high will the ball bounce, and
through what horizontal distance will the ball move, before hitting the floor again?
