A 116.0 g ball is dropped from a height of 2.75 m, bounces on a hard floor, and rebounds to a height of 1.82 m. The impulse received from the floor is shown below. What maximum force does the floor exert on the ball if it is exerted for 7.00 ms?
calculate vi, vf from the heights...remember that they are OPPOSITE signs.
when calculating the velocities from the heights, what time interval would you use
and would the force be positive or negative
