Mass m = 0.1 kg moves to the right with speed v = 0.45 m/s and collides with an equal mass initially at rest. after this inelastic collision the system retains a fraction = 0.86 of its original kinetic energy. if the masses remain in contact for 0.01 secs while colliding, what is the average force in n between the masses during the collision?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° 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.)
