The coyote, whose mass is 20.0kg, is chasing the roadrunner when the coyote accidentally runs off the edge of a cliff and plummets to the ground 30.0m below. What force does the ground exert on the coyote as he makes a coyote-shaped dent .420m deep in the ground?
I know that he hits the ground with a force of 6,000J becasue the PE=mgh at the top, Assuming that none of his energy is lost to air resistance he will hit the ground with that same force because all of the potential energy will be converted into kinetic energy. I am just not sure how to get the force. I know F=ma but that seems just to simple.
Any help at all will be appreciated.
Thanks for looking,
Steve
