A stone is dropped from a cliff. Its speed after it has fallen 100 m is:
A. 9.8 ms-1

B. 44.2 ms-1

C. 19.69 ms-1

D. 98 ms-1

Answer :

The stone is dropped from the cliff. So,

Initial Speed = u = 0

Distance = s = 100 m

Final Speed = v

Acceleration = a = g = 9.8 ms-2


v = 44.27 ms-1

Hence, option B is correct.
