A 47.1 kilogram girl is standing on a 162 kilogram plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.49 meter per second relative to the ice surface in the direction of the positive x-axis.
Determine the velocity of the plank relative to ice surface?
Find the velocity of the girl relative to the plank?
For each situation, state whether the collision is elastic or inelastic. If it is inelastic, state whether it is totally inelastic or not? You drop a ball from your hand. It collides with the floor and bounces back up so that it now reaches your hand..
