ANSWER BOTH QUESTIONS CORRECTLY AND RECEIVE 5 STARS


2__________________________________________________________

A billiard ball moving at 5.40 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.58 m/s at an angle of 32.0 degree with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude m/s direction degree (with respect to the original line of motion ) A neutron in a nuclear reactor makes an elastic, head-on collision with the nucleus of a carbon atom initially at rest. What fraction of the neutron's kinetic energy is transferred to the carbon nucleus? (The mass of the carbon nucleus is about 12.0 times the mass of the neutron.) The initial kinetic energy of the neutron is 1.30 x 10-13 J. Find its final kinetic energy and the kinetic energy of the carbon nucleus after the collision J neutron carbon nucleus J
