estion 3 of 4 Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 66.3 N, Jill pulls with 84.5 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 147 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey. magnitude of the net force: What is the direction of the net force? Express this as the angle from straight ahead between 0° and 90°, with a positive sign for angles to the left and a negative sign for angles to the right. direction of the net force: hp insert prt sc 112 f11 f1o 17 18 f9 144 t5 f6 10 IDI backspac & 5 P

estion 3 or 9 A heavy sled is being pulled by two people, as shown in the figure. The coefficient of static friction between the sled and the ground is Hs = 0.643, and the kinetic friction coefficient is µy = 0.403. The combined mass of the sled and its load is m = 276 kg. The ropes are separated by an angle o = 23.0°, and they make an angle 0 = 32.7° with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension required to get the sled moving? minimum rope tension: If this rope tension is maintained after the sled starts moving, what is the sled's acceleration? acceleration: m/s2
