Question

11.) You are playing a game of billiards and are trying to shoot the 8-ball into the corner pocket. You hit the cue-ball with so that it moves at 2 m/s in the positive x-direction toward the 8-ball. Just after collision, the 8-ball moves at 1 m/s at an angle of 30 degrees above the x-axis. What is the momentum vector of the cue-ball just after collision? Assume the mass of each ball is 0.2 kg. a. $<0.23, -0.1>$ b.) $<0.1, -0.23>$ c.) $<0.23, 0.1>$

Step 1

The initial momentum vector is given by the product of the mass and the velocity vector. Since the cue-ball moves at 2 m/s in the positive x-direction, the initial momentum vector of the cue-ball is <0.4, 0>. Show more…
