A mass m = 0.851 kg cart standing over a horizontal air track is attached to a string as it is shown in the figure. The string passes over a pulley of mass M = 1.45 kg and radius R = 40,4 cm (I= 1/2 MR-) and is pulled with a constant force F, as shown in the figure. If the air passing through the track is turned off, what is the magnitude of the constant force F that will accelerate the cart to an acceleration a = 3.64 m/s ? The static and kinetic friction between the cart and the air-track are u, = 0.75 and u = 0.4 respectively. (q715) a) 09.07 N b) O5.74 N c) 03.44 N d) O8.1 N
