1) A student measures the acceleration of a disk with 12 cm radius. She attaches a 150 g mass to the string and winds it around a 1 cm radius axle. When the mass drops, the tension from its weight creates an angular acceleration of 1.35 radians/s² on the disk. (This refers to sections 1.1 through 1.4 and utilizes the equations in the theory.) a) Calculate the moment of inertia of the disk. b) Calculate the mass of the disk.
A vinyl record spins freely on a frinctionless turntable. The mass of the record is 0.10 kg, the radius is 0.10 m, the rotational inertia is 5.0 x 10-4 kgm2 and it rotates with angular speed of 4.7 rad/s. A 0.024 kg piece of clay falls on the edge of the record. Determine the angular speed of the record right after the clay sticks to it. Use conservation of momentum.
1. In the figure below, block 1 has a mass of m1 = 450 g and block 2 has a mass of m2 = 500 g. The pulley, which is mounted on a horiztonal axle with negligible friction through its center, has a radius of 5.00 cm. When released from rest, block 2 falls without the cord slipping on the pulley, travelling 75.0 cm before it reaches a speed of 0.300 m/s. What is the rotational inertia of the pulley? m2
