Determine the angular acceleration of the rod the instant the rope and pulley system have pulled the rod through an angle of = 3.10. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) Learning Goal: To apply the equations of motion to a system that involves rotation about a fixed axis and to use this information to determine key characteristics. The slender rod AB shown has a mass of m = 75.0 kg and is being supported by a rope and pulley system stationed at C. Starting from rest (in the position shown), the rope and pulley system tug on the rod causing it to rotate about A. The torque applied to the pulley is T = 2.45 kNm and has an effective moment arm of r = 0.160 m. The dimensions shown in the figure are = 2.20 m and h = 1.90 m. Assume the pulley is frictionless and massless. (Figure 1) Submit Figure 1 of 1 Value Units Part B - Normal Component of the Reaction at A ?

The car shown has a mass of m 1000 kg and a center of mass located at G. The coefficient of static friction between the wheels and the road is u, = 0.210. The dimensions are a = 1.25 m, b = 1.75 m, and c = 0.310 m. Assume the car starts from rest, the wheels do not slip on the road, and that the car experiences constant acceleration. Neglect the mass of the wheels. (Figure 1) Determine the shortest time it takes the car to reach a speed of v = 86.0 km/h, starting from rest, if the engine drives only the front wheels.
