Snail velocity final problem

Postby paytonm1H » Sun Dec 09, 2018 2:55 pm

When given the momentum of a gamma ray photon, how do you find the velocity of a 200g snail? How can photons have momentum when they are massless?

Set KEsnail=Ephoton
so .5mv^2=pc then solve for v

I looked at this question for so long. Why a snail?

Do you remember the exact wording of the question? What info was given about the gamma ray? Would it have been possible to find E(photon) using E=hv and then using that as the Ek for the snail?
