A 160 lb person is being pulled on a tube in the snow by a four wheeler when the four wheeler starts to spin at 3 rad/s. Initially, the person on the tube is 12 feet from the center of rotation when the towing rope gets wrapped around the axle and begins to pull in at 3 ft/s. Determine the velocity of the person and the tube when they are 4 feet from the center of rotation. Neglect the mass of the four wheeler, tube, and towing rope. Assume the tube is on a smooth surface and that angular momentum is conserved. (108.0 ft/s)

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
