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

In a tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the light, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the tight, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction?
