Auniform disk with mass m = 9.11 kg and radius r = 1.37 m lies in the x-y plane and centered at the origin. three forces act in the +y-direction on the disk: 1) a force 319 n at the edge of the disk on the +x-axis, 2) a force 319 n at the edge of the disk on the –y-axis, and 3) a force 319 n acts at the edge of the disk at an angle θ = 32° above the –x-axis. 1) what is the magnitude of the torque on the disk about the z axis due to f1? n-m submit 2) what is the magnitude of the torque on the disk about the z axis due to f2? n-m submit 3) what is the magnitude of the torque on the disk about the z axis due to f3? n-m submit 4) what is the x-component of the net torque about the z axis on the disk? n-m submit 5) what is the y-component of the net torque about the z axis on the disk? n-m submit 6) what is the z-component of the net torque about the z axis on the disk? n-m submit 7) what is the magnitude of the angular acceleration about the z axis of the disk? rad/s2 submit 8) if the disk starts from rest, what is the rotational energy of the disk after the forces have been applied for t = 1.5 s? j submit
