A billiard ball with a mass of 0.15 kg is moving with a velocity of < 5, 0, 0 > m/s. It collides with a 2nd billiard ball of mass 0.20 kg initially moving at < -7, 0, 0 > m/s. After the collision, you observe the 2nd billiard ball moving at < 0.13, 0, 0 > m/s. a) What is the velocity of the 0.15 kg billiard ball after the collision? b) What is the vector change in momentum...

A billiard ball of mass = 300.0 g moving with an initial speed of 1.80 m/s strikes a second ball of mass mg 400.0 g initially at rest, As a result of the collision, the first ball is deflected off at an angle of 25.0 0 with a speed of 1.00 m/s. Do not assume this is a perfect collision, (a) Taking the x-axis to be the original direction of the motion of ball A, write down the equations of...
