- A 1 555-kg automobile has a wheel base (the distance between the axles) of l = 2.85 m. The automobile's center of mass is on the centerline at a point 1.35 m behind the front axle. Find the force exerted by the ground on each wheel. Part 1 of 3 - Conceptualize Since the center of mass is located in the front half of the car, there should be more force on the front wheels than the rear ones. The sum of the wheel forces must equal the weight of the car. Part 2 of 3 - Categorize Use the figure as a force diagram. Apply Newton's second law and sum the torques to find the unknown forces. l Part 3 of 3 - Analyze The torque about the front axle is zero, so we have Στις = 0 = (d Fg) - l (2F₁). Thus the force at each rear wheel is given by d F F₁ = 2Ff g || d 21 2F, m)(1. X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step da N. Since the sum of the wheel forces equals the weight of the car, we have 2F₁ + 2F₁ = Fg.…A system comprised blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with μk=μk= 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its acceleration.A Block A with mass mĄ rests on a horizontal tabletop, while block B with mass mg hangs from a string of negligible mass that passes over a pulley and attaches to block A, as shown above. The pulley has negligible mass and rotates with negligible friction about its axle. The blocks are at rest due to friction between block A and the tabletop. The coefficient of static friction between block A and the tabletop is u (mu), where u < 1.
- A motorcycle accelerates from rest, and both the front andrear tires roll without slipping. (a) Is the force exerted by theground on the rear tire in the forward or in the backward direction? Explain. (b) Is the force exerted by the ground on the fronttire in the forward or in the backward direction? Explain. (c) If themoment of inertia of the front tire is increased, will the motorcycle’s acceleration increase, decrease, or stay the same? ExplainA diver of mass 62.0 kg stands on one end of a diving board of mass 27.9 kg, as shown in the diagram. Everything is in equilibrium (since nothing is moving). What is the magnitude of the support force on the opposite end of the diving board? 757 N 1,353 N 1,082 N 1,624 NA 1.5 kg block is connected by a rope across a 50-cm-diameter, 2.0 kg pulley, as shown. There is no friction in the axle, but there is friction between the rope and the pulley; the rope doesn’t slip. The weight is accelerating upward at 1.2 m/s2. What is the tension in the rope on the right side of the pulley?
