An aerialist on a high platform holds onto a trapeze attached to a support by an 8.7-m cord. (see the drawing.) just before he jumps off the platform, the cord makes an angle of 44° with the vertical. he jumps, swings down, then back up, releasing the trapeze at the instant it is 0.87 m below its initial height. calculate the angle θ that the trapeze cord makes with the vertical at this instant.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
