Question

A body standing near the edge of a cliff 120 m above a river throws a stone downward with a speed of 10 ms -1 Find : (i) with what speed will the stone hit water (ii) How long will it take to descend?

Answer 1

Answer:

i) same speed

ii) 12s

Step-by-step explanation:

i) the speed of the stone remains the same

ii) distance = 120m

speed = 10ms^-1

time = t

t = d/s

t = 120/10

= 12s
