A constant torque of 23 N-m is applied to a shaft that is rotating with a CW angular velocity of 22.6 rad/s. Determine the time required to reverse the direction of motion and achieve a CCW rotation of 22.6 rad/s.

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.)
