Question

I am getting stuck with the algebra solving for V2f/getting the wrong answer, but i'm not sure where im going wrong-- please show all steps in a handwritten solution. Thank you!!

A proton that has a mass m and is moving at 310 m/s in the +î direction undergoes a head-on elastic collision with a stationary carbon nucleus of mass 12m. Find the velocities of the proton and the carbon nucleus after the collision. Vp m/s î V carbon = m/s î eBook

Answer 1

, biven, (mp) mass of proton = m Vpi = 310m/s and , (mc) of carbon = 12m vei-omis - Vef Voir Aster Before collision collision use conservation before and after are given as- of linear momentum collision, final velocities - (mp - mc) Noi Vpf = (mp+ me) Npf = m - 12 m mt 12m x 3lomis spf= lim 13 m x 3lomis - 262. 3n And 4 2 mb vb mpt mc Nef= 2 m x 3lomis 147.7 m/s (A) m+12m
