Question
Transcribed Image Text:The drawing shows two identical systems of objects; each consists of the same three
small balls connected by massless rods. In both systems the axis is perpendicular to the
page, but it is located at a different place, as shown. The same force of magnitude F is
applied to the same ball in each system (see the drawing). The masses of the balls are
m₁ = 9.4 kg, m₂ = 6.9 kg, and m3 = 7.7 kg. The magnitude of the force is F = 495 N. (a) For
each of the two systems, determine the moment of inertia about the given axis of
rotation. (b) Calculate the torque (magnitude and direction) acting on each system. (c)
Both systems start from rest, and the direction of the force moves with the system and
always points along the 4.00-m rod. What is the angular velocity of each system after
5.39 s?

- 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.arrow_forwardThe figure below shows a claw hammer being used to pull a nail out of a horizontal board where ? = 27.3°. The mass of the hammer is 1.00 kg. A force of 165 N is exerted horizontally as shown, and the nail does not yet move relative to the board. Assume the force the hammer exerts on the nail is parallel to the nail. A hand uses a hammer to pull a nail out of the ground. The head of the hammer is curved and touches the ground at a single point of contact at the center of the head. The nail in the ground makes an acute angle ? clockwise from the vertical. The nail is hooked in the hammer claw 5.00 cm horizontally to the left of the hammer head's point of contact to the ground. The hand pulls the hammer handle horizontally to the right 30.0 cm above the ground with a force vector F.(a) Find the force exerted by the hammer claws on the nail.magnitude kNdirection ° above the horizontal (b) Find the force exerted by the surface on the point of contact with the hammer head.( î + ĵ)…arrow_forwardA tightrope walker is walking between two buildings holding a pole with length L = 16.5 m, and mass mp 17.5 kg.

- 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.arrow_forwardMasses m₂, m₂, m3 and om are connected together as shown in the figure below.

- In the figure, a man is trying to get his car out of mud on the shoulder of a road. He ties one end of a rope tightly around the front bumper and the other end tightly around a utility pole 29 m away. He then pushes sideways on the rope at its midpoint with a force of 550 N, displacing the center of the rope 0.28 m from its previous position, and the car barely moves. What is the magnitude of the force on the car from the rope? (The rope stretches somewhat.)arrow_forwardplease include free body diagrams, thank you!arrow_forwardIn the figure, a man is trying to get his car out of mud on the shoulder of a road.
