Question
A body standing at the loop of a tower of 20 m height drops a stone . Assuming g = 10 ms-2, the velocity which it hits ground is
Options
A.10.0 m/s
B.20.0 m/s
C.40.0 m/s
D.5.0 m/s
Solution
Here u = 0, g = 10 ms-2, h = 20 m
Let v be the velocity with which the stone hits the ground
∴ v2 = u2 + 2gh
or, v2 =
= 20 m/s (∵ u = 0)
Let v be the velocity with which the stone hits the ground
∴ v2 = u2 + 2gh
or, v2 =
= 20 m/s (∵ u = 0)Create a free account to view solution
