Aball is thrown straight up from the ground with speed v0. at the same instant, a second ball is dropped from rest from a height h, directly above the point where the first ball was thrown upward. there is no air resistance. a) find the time at which the two balls collide. express your answer in terms of the variables h, v0, and appropriate constants. b) find the value of h in terms of v0 and g so that at the instant when the balls collide, the first ball is at the highest point of its motion. express your answer in terms of the variables v0 and g.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0Ā° above the horizontal. it then moves 137 ft at an angle of 48.0Ā° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
