In a stage production of Peter Pan, the 58 kg actress playing Peter has to fly in vertically, and to be in time with the music, she must be lowered, starting from rest, a distance of 3.4 m in 2 s. Backstage, a smooth surface sloped at 48? supports a counterweight of mass m, as shown in figure below. What is the mass of the counterweight that must be used? The pulley is of negligible mass and is frictionless. The acceleration of gravity is 9.81 m/s 2. Answer in units of kg.
