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.
