A stunt performer swings on a 34.0 m long rope initially inclined at an angle of 40.0° with the vertical. (Assume the rope has negligible mass.) (a) What is the stunt performer's speed (in m/s) at the bottom of the swing if he starts from rest? m/s (b) What is the stunt performer's speed (in m/s) at the bottom of the swing if instead he pushes off with a speed of 4.40 m/s? m/s
