In a stage production of Peter Pan, the 61 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 2.6 m in 2.3 s. Backstage, a smooth surface sloped at 47 supports a counterweight of mass m, as shown in figure below. m 47° 61 kg 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/s². Answer in units of kg. What is the tension in the wire? Answer in units of N.
