Question

Jeanette is playing in a 9-ball pool tournament. She will
win if she sinks the 9-ball from the final rack, so she needs
to line up her shot precisely. Both the cue ball and the 9-
ball have mass m, and the cue ball is hit at an initial
speed of v₁. Jeanette carefully hits the cue ball into the 9-
ball off center, so that when the balls collide, they move
away from each other at the same angle from the
direction in which the cue ball was originally traveling (see
figure). Furthermore, after the collision, the cue ball moves
away at speed uf, while the 9-ball moves at speed vg. (
Figure 1)
For the purposes of this problem, assume that the collision
is perfectly elastic, neglect friction, and ignore the spinning
of the balls.

A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jumps from the first log onto a second. After landing safely on the second log, she slows down and ends up standing on the second log. Both logs both have masses of 150 kg each and the mass of the lumberjack is 70 kg. The lumberjack reaches a speed of 7.0 m/s relative to the shore during her jump. What is the speed of the lumberjack after she has stopped on the second log? You may assume the drag of the water on the logs is very small. Please answer in units of m/s.
