Question

the total time it takes to return to the surface oleh
14. A stone is released from the top of a tower of height 19.6 m
Calculate its final velocity just before touching the ground
pward with an initial velocity of​

Answer 1

Explanation:

Initial Velocity u=0

Fianl velocity v=?

Height, s=19.6m

By third equation of motion

v²=u²+2gh

v²=0+2×9.8×19.6

v²=384.16

v=√384.16

v=19.6m/s
