The velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.

Velocity of the stone

The velocity of the stone at the given displacement is calculated as follows;

K.E = ΔP.E

¹/₂mv² = mgh

v = √2gΔh

v = √[2(9.8)(7.7 - 5.25)]

v = 6.93 m/s

Thus, the velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.
