1) A cart having mass mc is connected to a hanging mass mp as shown in the figure. When the cart is released from rest, it accelerates towards the pulley. mn (There is no friction on the table surface or in the pulley. The masses of pulley and the string are negligible. g=9,8 m/s²) For m.=0,25 kg and mp = 20gr a) What would be the acceleration of the cart ? b) What would be the acceleration if an extra mass of 0.25 kg was placed on the cart?
