Consider the 639 n weight held by two cables. shown below. the left-hand cable had ten-. sion t2 and makes an angle of 53 with the. ceiling. the right-hand cable had tension t1. and makes an angle of 49 with the ceiling. a) what is the tension in the cable labeled. t1 slanted at an angle of 49? b.) and t2 slanted at

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.
