An aerialist on a high platform holds onto a trapeze attached to a support by an 7.9-m cord. (See the drawing.) Just before he jumps off the platform, the cord makes an angle of 37° with the vertical. He jumps, swings down, then back up, releasing the trapeze at the instant it is 0.57 m below its initial height. Calculate the angle θ that the trapeze cord makes with the vertical at this instant.

Answer 2

An aerialist on a high platform holds onto a trapeze attached to a support by an 8.0-m cord. (See the drawing.) Just before he jumps off the platform, the cord makes an angle of 36° with the vertical. He jumps, swings down, then back up, releasing the trapeze at the instant it is 0.60 m below its initial height. Calculate the angle θ that the trapeze cord makes with the vertical at this instant.
