using Anti-derivative A stone is dropped off a cliff and hit the ground with a speed of 120 ft/s . a) what is the equation for acceleration a(t), velocity v(t), and displacement/ position s(t)? b) what is the height of the cliff ?

Question

amistre64 · Answer

v(t) = -32t + C = 120

amistre64 · Answer

v(0) = 0; v(t) = -32t

-32t = 120, when t= ?

amistre64 · Answer

t = 15/4

s(t) = -16(15/4)^2 + Hi = 0, when Hi = ?

amistre64 · Answer

Hi = 225 ft

s(t) = -16t^2 + 225
v(t) = -32t
a(t) = -32
