Question

O/6 points The figure below shows an arrangement with an air track, in which a cart is connected by a cord to a hanging block. The cart has mass m10.680 kg and its center is initially at xy coordinates (-0.500 m, 0 m). The block has mass m20.260 kg and its center is initially at xy coordinates (O, -0.100 m). The mass of the cord and pulley are negligible. The cart is released from rest, and both cart and block move until the cart hits the pulley. The friction between the cart and the air track and between the pulley and its axle is negligible. HRW8 9.P013 My Notes Ask Your Te 7m n2 (a) In unit-vector notation what is the acceleration of the center of mass of the cart block system? X m/s2 (b) What is the velocity of the center of mass as a function of time t? (Assume t is in seconds.) inf: (c) Sketch the path taken by the systems center of mass. (Do this on paper. Your instructor may ask you to turn in this sketch.) (d) If the path is curved, type counterclockwise from the positivex axis upward if it bulges upward to the right or downward it bulges downward to the left. If the path is straight, give its angle, in degrees
