An action figure is placed on a toy car, which is initially at rest. Then the action figure moves through 4 time intervals: The car is pushed until it hits a wall. Then, the action figure slides down a ramp. The action figure flies off of the ramp and hits a wall at the peak of its trajectory, momentarily coming to a complete stop. Finally, the action figure falls into the toybox and comes to rest. Assume that all surfaces, except the final wall, have nonzero coefficients of static and kinetic friction. For each time interval, including the endpoints, determine whether the total work done on the action figure by gravity (?g), normal forces (?N), and friction (?f) is positive, negative, or zero. Neglect drag. The motion of a toy army guy action figure is shown in four different time intervals. The toy is stiff and has a base for standing upright.
