we are given that a stone dropped from well from rest, and the wall is 50 m deep, and we are given acceleration due to gravity or simply acceleration as 9.8 m/s^2
U=0
V= we need to find
t=we need to find
s= 50 m
a= 9.8 m/s^2
Using 3rd equation of motion
V� = U� + 2as
subsituting the values, we get
V� = 0� + 2 x 9.8 x 50
V� = 0� + 2 x 9.8 x 50
V� = 19.6 x 50
V� = 980
V = √980
V = 31.30 metre
using 1st equation of motion
V = U + at
subsituting the values, we get
31.30= 0 + 9.8 x t
31.30= 0 + 9.8 x t
31.30/9.8 = t
3.19 seconds = t
from this we get time equal to 3.19 seconds

Using 3rd equation of motion
V² = U² + 2as
V² = 0² + 2 x 9.8 x 50
V² = 19.6 x 50
V² = 980
V = √980
V = 31.30 meter
using 1st equation of motion
V = U + at
31.30= 0 + 9.8 x t
31.30 ÷ 9.8 = t
3.19 second = t
V² = U² + 2as
V² = 0² + 2 x 9.8 x 50
V² = 19.6 x 50
V² = 980
V = √980
V = 31.30 meter
using 1st equation of motion
V = U + at
31.30= 0 + 9.8 x t
31.30 ÷ 9.8 = t
3.19 second = t
