You are at the top of a 500 meter tower and drop a 5-kg hammer. Calculate the potential and kinetic energies and total energy at the end of each second of free fall and at the moment of impact.
Elasped D=5t2 V= a t PE = mgh KE =1/2 mv2 KE + PE mv
Time m m/s J J J N
This solution provides calculations (in Excel) for potential, kinetics, and total energies in free fall and during moment of impact.
