Jimmy is at the bottom of a hill while Billy is on the hill a distance 30 m up the hill from the bottom. Jimmy is at the origin of an xy coordinate system, and the line that follows the slope of the hill has an equation y = (0.18) x. Jimmy throws an apple to Billy at an angle of 50° with respect to the horizontal. The acceleration of gravity is 9.8 m/s2. With what speed v0 must he throw the apple to reach Billy?
