Recap - Billiards
Part of the Mechanics section of Coddy's Physics journey. Lesson 71 of 94.
Challenge
A cue stick strikes a 0.17 kg cue ball at rest with an impulse of 0.34 N·s along the x axis. The cue ball rolls into an object ball of the same mass at rest, and afterwards moves at 1 m/s, 60° above the x axis. Find the x velocity v2x of the object ball.
