SUMMARY
The discussion analyzes the impact of a .45kg piece of putty dropped from a height of 2.5m onto a flat surface, concluding that the average force exerted on the putty by the surface can be calculated using the formulas for velocity (V=d•t) and force (F=m•a). The putty comes to rest in 0.30 seconds, allowing for the calculation of acceleration and subsequently the average force. The impulse delivered by the surface is a critical factor in determining the force experienced by the putty upon impact.
