Question

An illumination flare is dropped over the edge of a 150 meter cliff. How long will it take for it to free fall to the bottom? Round your answer to the nearest tenth.

Answer 1

initial velocity = 0
distance = 150
acceleration = 9.8 m/s/s
time = ???

Answer 2

s = ut + 1/2 at^2

Answer 3

initial velocity = 0 (u)
distance = 150 (s)
acceleration = 9.8 m/s/s (a)
time = ??? (t)

Answer 4

okay i think i got it
