A neutron collides elastically with a helium nucleus (at rest initially) whose mass is four times that of the neutron. The helium nucleus is observed to rebound at an angle '2 = 42° from the neutron's initial direction. The neutron's initial speed is 6.8 105 m/s.

a. Determine the angle at which the neutron rebounds, '1, measured from its initial direction. (in degrees) b. What is the speed of the neutron after the collision? c. What is the speed of the helium nucleus after the collision?

A proton collides elastically with another proton that is initially at rest. The incoming proton has an initial speed of 2.00e5 m/s and makes a glancing collision with the second proton (at close separations, the protons exert a repulsive electrostatic force on each other). After the collision, one proton moves off at an angle of 40.0 degrees to the original direction of motion and the second deflects at an angle of __ to the same axis. Find the final speeds...
