Question

a stone is dropped down a deep well from rest the well is 50 metre deep. how long will it take to reach the the bottom of the well ?given acceleration 9.8 m/s²​

Answer 1

Answer:

Given, hieght of the well = 50 m.

acceleration due to gravity = 9.8 m/s^2.

s = ut + 1/2 at^2

initial velocity u, = 0

50 = 1/2 × 10 × t^2

t^2 = 100 / 9.8

t = √ 10.2

t = 3.19 seconds
