A tоy cаr with а mаss оf 0.10 kg mоves around a circular track on the floor with a radius of 0.5 m. At the instant shown the car has a constant speed of 5 m/s. Using a view from above, draw the path of the car; and the velocity, tangential acceleration, and centripetal acceleration directions (if any of these are zero just leave them those blank). Calculate the acceleration vector of the car. Calculate the net force vector acting on the car (since we’re calculating net force you don’t need to draw a free body diagram).
