Agrasshopper makes four jumps. the displacement vectors are (1) 38.0 cm, due west; (2) 27.0 cm, 42.0° south of west; (3) 20.0 cm, 66.0° south of east; and (4) 23.0 cm, 77.0° north of east. find (a) the magnitude and (b) direction of the resultant displacement. express the direction as a positive angle with respect to due west.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
