Question

(a) How long does the stone take to reach its highest point?
time =
(include units)

(b) What is its maximum height?
height =
(include units)

(c) How long before the stone hits the beach?
time =
(include units)

(d) What is the velocity of the stone on impact?
velocity =
(include units)

A stone thrown upward from the top of a 132 ft cliff at 164 ft/sec eventually falls to the beach below. (For this problem take the acceleration due to gravity to be {}^2; take upwards to be a positive direction.) (a) How long does the stone take to reach its highest point? time = (include units) (b) What is its maximum height? height = (include units) (c) How long before the stone hits the beach? time = (include units) (d) What is the velocity of the stone on impact? velocity = (include units) g = -32 ft/sec

Explanation / Answer

At top, v=0
u = 164ft/s
use newton's 1st law,
v = u + at

164 = 32t
t = 5.125 sec
