A 250-kg ball moving to the right at a velocity of 383 ms, Ask an Expert

Academics

A 2.50-kg ball, moving to the right at a velocity of +3.83 m/s on a frictionless table, collides head-on with a stationary 8.10-kg ball. Find the final velocities of (a) the 2.50-kg ball and of (b) the 8.10-kg ball if the collision is elastic. (c) Find the magnitude and direction of the final velocity of the two balls if the collision is completely inelastic.
