A stone thrown upward from the top of a 90 ft
cliff at 134 ft/s eventually falls to the
beach below. (For this problem take the acceleration
due to gravity to be g = -32 \ \mathrm{ft/s^2} ; take
upwards to be a positive direction.)

**(a)**
How long does the stone take to reach its highest point?

time =

**(b)**
What is its maximum height?

height =

**(c)**
How long before the stone hits the beach?

time =

**(d)**
What is the velocity of the stone on impact?

velocity =
