platforms about 35 m above the water, but they must clear
rocky outcrops at water level that extend out into the water
5.0 m from the base of the cliff directly under their launch
point. See Fig. 3-53. What minimum pushoff speed is neces-
sary to clear the rocks? How long are they in the air?

- #4) A baseball is launched by mechanical means nearly vertically upward from a point near the edge of the roof of Morrow Library. It just misses the edge of the roof on the way down (when it is in free fall) and passes a point a distance 10.0 m below its starting point at a time 4.75 s. Air resistance may be ignored. Use the magnitude of the acceleration due to gravity as 9.80m/s² and report answers to 3 sig figs for parts A-E. Consider this as a one-dimensional problem. Show starting equations, do algebra first, and then plug numbers in last for each part. A) What is the initial velocity of the baseball? B) How high does it rise above its starting point?
