Impact Force from Falling Object - Georgia State University

If an object of mass m= kg is dropped from height h = m, then the velocity just before impact is v = m/s. The kinetic energy just before impact is equal to its gravitational potential energy at the height from which it was dropped: K.E. = J. But this alone does not permit us to calculate the force of impact!
