An aerialist on a high platform holds onto a trapeze attached to a support by an 8.9−m cord. (See the drawing.) Just before he jumps off the platform, the cord makes an angle of 45∘ with the vertical. He jumps, swings down, then back up, releasing the trapeze at the instant it is 0.79 m below its initial height. Calculate the angle θ that the trapeze cord makes with the vertical at this instant.

A ball is attached to a cord of length L, which is tied to a frame attached to a truck bed as shown in figure (a), below. The ball-truck system is initially traveling to the right at constant speed vi, with the cord vertical.

The sphere at A is given a downward velocity v0 of magnitude 5.7 m/s and swings in a vertical plane at the end of a rope of length / = 2 m attached to a support at O. Determine the angle θ at which the rope will break, knowing that it can withstand a maximum tension equal to twice the weight of the sphere. The rope will break at an angle of ∘.
