A block of mass m2 hangs from a rope. The rope wraps around a pulley of rotational inertia I, radius R, and then attaches to a second mass m1, which sits on a frictionless table as shown in figure. Derive an equation of the acceleration of the blocks when they are released?
Two blocks are connected to a rope that passes over a pulley shaped like a disk, as shown. The pulley has a mass of 3.40 kg, a radius of 11.0 cm and is on a frictionless axle. Block A has a mass of 9.00 kg and block B has a mass of 20.0 kg. The system is released from rest when block A is 1.40 m above the floor В a) How fast is Block A moving when it has...
A 2.85 kg block is attached to a rope and wrapped around a disc- shaped pulley of radius 0.121 m and mass 0.742 kg. If the block is allowed to fall, (a) What is its linear acceleration? (b) What is the angular acceleration of the pulley? (c) How far does the mass drop in 1.50 s?
2. The pulley (disk) has a radius "R" and a mass "m". The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block A and the surface is "u. The system is released from rest and block B descends. Block A has a mass "2m" and block B has a mass "m Write out the forces and torque equations. Given [R, m, h, ], Determine: a. The acceleration...
By means of a rope whose mass is negligible, two blocks are suspended over a pulley, as the drawing shows, with m1 = 10.7 kg and m2 = 46.0 kg. The pulley can be treated as a uniform, solid, cylindrical disk. The downward acceleration of the 46.0-kg block is observed to be exactly one-half the acceleration due to gravity. Noting that the tension in the rope is not the same on each side of the pulley, find the mass of...
A small block of mass m2 hangs from a massless rope wrapped around the inner cylinder of a pulley with inner radius of R2. The moment of inertia of the entire pulley is I = 4m2(R2)2. Another block m1= m2 is connected to the outer cylinder of the pulley via a horizontal massless rope wrapped around the outer cylinder of the pulley with radius R1=2R2. The coefficient of kinetic friction between the block and the horizontal surface is μk =...
19. A rope is wrapped around a pulley that can be modelled as a solid disk of mass M = 4.0 kg and radius R 0.40 m. The pulley is initially at rest. M Your hand applies a force F = 15 N on the free end of the rope, pulling it down. What is the rotational speed of the disk after you pulled the free end of the rope the distance of 1.2 m? A) 10.6 rad/s B) 12.8...
explain how please. A 8 kg block is attached to a rope that is wrapped many times around the rim of a flywheel (pulley), which is considered as uniform disk of diameter 0.5 meters and mass 4 kg . When the block is released the rope unspools without slipping. What is the acceleration of the block in m/s2?
In the figure below, a rope is wound around a horizontal disk (Ma 3.10 kg and Ra 17.0 cm). passed across a pulley (Ic 50.0 kg cm2 and Re 8.00 cm), and connected to a hanging 4.00 kg mass. Initially, the mass is held in place, and the system is at rest. The mass is then released and descends in response to the force of gravity. The rope does not slip on the pulley or the horizontal disk. Both the...
) A 2 kg block is attached to a rope. The rope is wound around a pulley which has a radius of 0.2 m. You do not know the mass of the pulley, or the geometry of the pulley. The block is released from rest, and you notice it has a speed of 3 m/s after falling 1.5 m. a) What is the angular velocity of the pulley when the speed is 3 m/s? b) Use the fact that energy...
