Hey all, I am in need of desperate help, any comments would be a huge help! thanks.(adsbygoogle = window.adsbygoogle || []).push({});

A proton moving at 3x10^5 m/s [E], strikes a helium nucleus at rest. If the collision is perfectly elastic, find the velocities of each after the collision. Assume the collision is 1 dimensional.

A tennis ball of mass m and speed v strikes a wall at 45degree angle and rebounds with the same speed at 45degrees. What is the impulse given the wall? [Hint: Magnitude and Direction are needed]

Thanks for any help,

Jeremy
