A circular disk with a radius of 0.37 m is subject to 2 tangentially applied forces. The disc is xed such that it will rotate about its center. Both forces produce a torque in the same direction. F1 = 4.9 N applied at the outer edge of the disc. F2 = 3.5 N applied at a distance of 0.28 from the center of the disc. What is the net torque on the disc? D Question 2 2 pts A circular disk with a radius of 0.51 m is subject to 2 tangentially applied forces. The disc is xed such that it will rotate about its center. Both forces produce a torque in the same direction. The mass of the disc is 0.57 kg. The moment of inertia of a disc is I 2 %MR2 F1 = 2.9 N applied at the outer edge of the disc. F2 = 4.2 N applied at a distance of 0.22 from the center of the disc. What is the angular acceleration of the disc? Question 3 2 pts A spherical shell with a mass of 1.76 kg and a radius of 0.37 m is rolling across the level ground with an initial angular velocity of 39.1 rad/s. It is slowing at an angular rate of 4.2 rad/$2. What is its rotational kinetic energy after 4.2 s? The moment of inertia of a spherical shell is I = gMR2 Question 4 2 pts A spherical shell with a mass of 1.63 kg and a radius of 0.45 m is rolling across the level ground with an initial angular velocity of 38.4 rad/s. It is slowing at an angular rate of 2.52 rad/52. What is its total kinetic energy after 4.1 s? The moment of inertia of a spherical shell is I = gMR2
