Question

If a stone is dropped from a cliff, what will be its speed after it has fallen 100m?

Consider acceleration= 10m/s​

Answer 1

Answer:

The stone is dropped from the cliff. So,

Initial Speed = u=0

Distance = s=100m

Final Speed = v

Acceleration = a = g = 9.8 sec2m

Now,

v2=u2+2as

v2=0+2∗9.8∗100

v=(2∗9.8∗100)

v=44.7secm
