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?
Concept - write equations of motion for the
block and the disk using Newton’s law of motion and solve to find
the acceleration as shown below***********************************************************************************************
Check the answer and let me know immediately if you
find something wrong or missing... I will rectify the mistakes asap
if any

Explain how please. A 15 kg block is attached to a rope that is wrapped many times around the rim of a flywheel (pulley) of radius 0.2 meters. When the block is released the rope unspools without slipping. If the acceleration of the block is 3.5, what is the rotational inertia of the flywheel (in kg·m2)?
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?
A block of mass M = 1.1 kg is attached to a string which is wrapped around a pulley. As the block accelerates due to gravity the pulley rotates clockwise. The pulley can be thought of as a thin cylinder of mass m = 0.5 kg and radius r = 0.26 m. Consider positive to be the block moving down and the pulley rotating clockwise. What is the downwards acceleration of the block? What is the angular acceleration of the...
ip a 1.2 kg block is tied to a string that is wrapped around the rim of a pulley of radius 7.1cm. the block is released from rest. EXPLAIN l, LhandlerSig Hide Timer Part A Assuming the pulley is a uniform disk with a mass of 0.31 kg, find the speed of th block after it has fallen through a height of 0.50 m Express your answer using two significant figures. 2 m/s Submit Submit Request Answer Part B 1033...
A light rope is wrapped several times around a large wheel with mass M= 18.0 kg and radius R= 0.750 m. the wheel rotates without friction about a horizontal axis. The free end of the rope is tiedto a suitcase (mass m= 3.00 kg). The siutcase is released from the rest and decends a height h=4.00m to reach the ground. We assume that (i) the wheel is a solid uniform disk and (ii) the rope unwinds without slipping. Find the...
A 250 kg disk of radius 1.5 meters has a rope wrapped around the rim. You pull on the end of the rope and increase the frequency of rotation by 1 Hz in 2 seconds. a. What is the angular acceleration in radians/s2? b. What is the force required to cause the acceleration in the last part?
A 1.5 block and a 2.5 kg block are attached to opposite ends of a light rope. The rope hangs over a solid, frictionless pulley that is 30 cm in diameter and has a mass of 0.75 kg. When the blocks are released, What is the acceleration of the lighter block? please with free body diagram
A mass m hangs from a string. The string is attached to a frictionless pulley of mass M and is wrapped around it many times around it. The hanging mass is released from rest from a height h above the floor. The pulley is a uniform disk. use the rotational and linear second laws to find the acceleration of the mass as it falls. I got a = 2mg/(2m+M). Is this correct? If, so please explain
A 16 kg block is attached to a cord that is wrapped around the rim of a wheel of radius 2 m and its hangs vertically, as shown. 1 9 16 CU 2. 3.9 4 9 m 32 The rotational inertia of the wheel is 32 kg mº. When the block is released and the cord unwinds, the magnitude of the down- ward acceleration
Problem #4 A 10 kg box resting on a horizontal, frictionless surface is attached to a 4 kg block by a thin light rope that passes over a frictionless pulley. The pulley has a shape of a uniform solid disk of mass 4.5 kg and a radius of 0.55 m. After the system is released 10 kg box moves to the right, 4 kg block moves down and the pulley rotates clockwise. Find: (a) the magnitude of the tension (in...
