An aerialist on a high platform holds on to a trapeze attached to a support by an 8.0-m cord as shown. As he jumps off the platform, the cord makes an angle of 41 with the vertical. He swings down, then back up, releasing the trapeze at the instant it is 0.75 m below the initial height. a) Calculate the angle @ that the trapeze cord makes with the vertical at this instant. b) Determine the aerialist's speed at the instant he releases the trapeze. ) The aerialist lands in a net 6 m below his release point. Calculate the aerialist's speed as he hits the net
