A pair of masses are attached by a string that runs over a pulley. The larger mass is on a frictionless incline that makes an angle of 18 degree with the ground. the smaller mass is hanging in the air off the pulley. the larger mass is given an initial velocity of 1.7 m/s up the incline which pulls the smaller mass up by .33 meters after .72 seconds. (the smaller mass is .112 kilograms). what is the mass of the larger masses?
