Help solving the speed for and electron, having same momentum as a proton at 0.62c??
A proton moves with a speed of 0.62c. Find the speed of an electron that has the same momentum. (Express the answer as the quantity of one minus a number times c.)
pp=pe
or
ypmpup=yemeue
Known:
mp= 938.27 MeV/c2
up= 0.62c
me=0.511 MeV/c2
Solve for yp= 1/sq rt 1-(0.62)2
yp= 1.27453
so...
(1.27453)*(938.27MeV/c2)*(0.62c) = (0.511MeV/c2)*(ye)*(ue)
(741.429 MeV/c2*c) = (0.511MeV/c2)*(ye)*(ue)
1450.937c = (ye)*(ue)
Now this is where I get confused with the algebra...and need help getting thru it.
Please help! I've been struggling for 2 days on this and have finally broken down. I have one more oppurtunity to give the correct answer.
Thanks for the help..appreciate it.
