A stone thrown upward from the top of a 108 ft cliff at 132 ft/sec eventually falls to the beach below. (For this problem take the acceleration due to gravity to be -32 ft/sec; take upwards to be a positive direction.)
a.) How long does the stone take to reach it's highest point?
b.) What is its maximum height?
c.) How long before the stone hits the beach?
d.) What is the velocity of the stone on impact?
