Question

a stone is drop from a plane find speed of a stone after 5 second, speed of a stone when it fallen through 1960 m , time taken falling through 1960m please answer fast​

Answer 1

Answer:

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
