Which one of the following equations would I use to find the momentum of the polevolter once he has let go of his pole? mv1+mv2=mv1+mv2 or mv1+mv2=(m+m)v

Thank you.

Hi Stephen!So wouldnt you use the momentum equations to see how much momentum the polevolter has once he lets go of the pole?

It's

So you'd just use conservation of

so you would have 1/2mv1^2 + 1/2kx^2 +mgh0= 1/2mv2^2 + 1/2kx^2 +mgh1?
