ᴀ stone pf mass 100 g is dropped from the top of a tower.It takes 2s to reach the ground. Evaluate the potential energy when it is at the top of the tower

Initial speed of the stone u=0m/s

Time taken by the stone to reach the ground t=4s

Height \:  of \:  the \:  tower  \: h = ut +  \frac{1}{2}  {at}^{2}

∴  H = 0 +  \frac{1}{2}  \times 10 \times  {4}^{2}

⟹  H=80m

Hope it helps you✌︎
