Homework Statement
I am trying to work out the force which a mass applies when it drops from a known height onto another object.
Homework Equations
F=ma
suvat:
v^2 = u^2 + 2as
F= change in momentum/time
and possibly KE= 1/2mv^2
The Attempt at a Solution
I don't think that F=ma applies exactly as this does not take into account where the mass is dropped from at all.. the force must be larger if the mass is traveling at a greater speed, surely?? This is the force the mass would apply if it was not moving..
I can work out the KE by finding the velocity at the moment of contact, but I don't know how to transfer this into a force. This is from a practical experiment so I don't actually have any time measurements =/ although I could estimate them by using suvat.
Thanks for any help.
