Homework Statement
A 2580 kg pile driver is used to drive a steel I-Beam into the ground. The pile driver falls 2.52 m before contacting the beam, and it drives the beam 5.58 cm into the ground before coming to rest.
Find the magnitude of the average force for the beam exerts on the pile driver while the pile driver is brought to rest.
Homework Equations
F=ma
The Attempt at a Solution
ok so looking at this problem the first thing that came to my head is that i need to find the proper force and divide in by the 5.58 cm converted to meters to get the magnitude of force.
So i plugged in F=ma F=(2580)9.8
giving me 25284
but I am not seeing where the 2.52 meters should come into play.
