Aglowing blue mote of mass 32.3 g is traveling east at 4.50 m/s when it collides and merges with another mote of mass 78.0 g that is traveling west at 1.12 m/s. find the velocity of the motes after they merge together (be sure to include direction).

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° 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.)
