Billiard ball a of mass 0.130 moving with speed 2.80, Ask an Expert

Academics

Q1. Billiard ball A of mass = 0.130 moving with speed = 2.80 strikes ball B, initially at rest, of mass = 0.150. Consequently of the collision, ball A is deflected off at an angle of 28.0 with the speed = 2.00.

Q2. A 44.2 kg girl is standing on a 149kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.52ihatbold m/s relative to the plank.
