In a stage production of peter pan, the 63 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 2.2 s. backstage, a smooth surface
sloped at 58◦ supports a counterweight of mass m. 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.
