A proton of mass m undergoes a head-on elastic collision with a stationary nucleus of mass 3m. The speed of the proton is 730 m/s. Find the velocity of the center of mass of the system.
Homework Answers
Vcm = m1v1 + m2 v2 / (m1 + m2 )
since momentum will be conserved so m1v1 + m2v2 will be same before and after collision
= m*730 /(4m)
=182.5 m/s

A proton travels directly (head on) towards a stationary lead nucleus, with an initial speed Vo, when the proton is a distance Xo from the nucleus. It undergoes an acceleration of magnitude a=kx^-2 directed away from the nucleus, where x is the distance from the proton to the nucleus and k is a positive constant. (Assume the lead nucleus remains stationary throughout.) (a) Give an expression for how the velocity of the proton depends on x. (It will also depend...

Consider a head-on elastic collision of a ‘bullet’ of rest-mass M with a stationary ‘target’ of rest-mass m. Prove that the post-collision γ-factor of the bullet cannot exceed (m2+M2 )/(2Mm). This means that for large bullet energies (with γ-factors much larger than this critical value), the relative transfer of energy from bullet to target is almost total.
