The Attempt at a Solution


im not sure but i think the answer is that they both have something to do with work..can someone help clarify..thanks

umm hello..anyone?
 
does like nobody no the answer?
 
What is the formula for momentum, and what is the formula for kinetic energy?
 
hi

Momentum = mv (mass x velocity)

Potential energy = mg∆h (mass x acceleration due to gravity x ∆ height)
Kinetic energy = 1/2 mv^2 ( 1/2 x mass x velocity squared)

work done = force x distance traveled in the direction of the force

since work done is energy

it follows that energy = force x distance

maybe you can derive a relationship from the information above

hope that helped

I am adding on that you may want to consider the Impulse-Momentum Theorum (it should make it easier to deal with force)
