Impact Force

Calculations are in Metric
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

K.E. = J.

But this alone does not permit us to calculate the force of impact!

If in addition, we know that the distance traveled after impact is
d = m, then the impact force may be calculated using the work-energy principle to be
Average impact force = F = N.
