A disk has mass M = 1.0 kg and radius, R = 0.3 m is free to rotate about a fixed axlethrough its center. Since the axle is fixed, the center of mass of the disk does notmove. The disk is initially not rotating. A student wraps a string 5 times around theperimeter of the disk and then pulls the string with a constant force of F = 2.0 N, asshown in the figure below.F= 2N ER=0.3mI=įmr?The student pulls on the string until it is completely unwound, and the string does not slip on thedisk as it is pulled. After the string has unwound, what is the angular speed of the disk w :OA.W = 54.9 radians/secOB.W = 32.8 radians/secOC.29 radians/secO Dw = 17.6 radians/sec6.3 radians/sec

Given Mass m = 1 Kg Radius r = 0.3 m No of wraps = 5 Force F = 2 N

An isolated system consists of a single object, which initially moves without friction at velocity ux along a horizontal x-axis. After an internal explosion, the object splits into two parts, A and B. The figure shows the masses and speeds of these parts immediately after the explosion. None of these objects rotates. 1.50 m s-¹ 2.00 kg A Final kinetic energy initial kinetic energy 3.50 m s-¹ - 3.00 kg What is the difference between the total final kinetic energy of A and B and the initial kinetic energy of whole object?

The two blocks are connected by a massless rope that passes through a pulley. Mass of first block is m1 = 1 kg, mass of the second block is m2= 5 kg. Mass of the pulley is M = 2 kg. Radius of the pulley is R= 10 cm. First block is placed on the 30 incline and the second block is hanging above the table at the height of 40 cm. Then, the system is released and the first block starts sliding up the incline and the second block starts falling toward the table. a) forces that apply to the pulley. b) pulley. Consider the pulley to be a disc and use disc's moment of inertia(/ = MR?/2) c) acceleration of the blocks.

A student stands on a platform that is free to rotate and holds two dumbbells, each at a distance of 65 cm from his central axis. Another student gives him a push and starts the system of student, dumbbells, and platform rotating at 0.50 rev/s. The student on the platform then pulls the dumbbells in close to his chest so that they are each 22 cm from his central axis. Each dumbbell has a mass of 1.00 kg and the rotational inertia of the student, platform, and dumbbells is initially 2.40 kg-m². Model each arm as a uniform rod of mass 3.00 kg with one end at the central axis; the length of the arm is initially 65 cm and then is reduced to 22 cm. What is his new rate of rotation?

Two kids are playing on a seesaw on the school playground. The first kid (of mass 50 kg) sits 2 meters from the fulcrum. The other child (who has a mass of 70 kg) sits on the other side of the seesaw. How far away from the fulcrum does the second child need to sit in order to balance the seesaw? Assume that the seesaw itself is weightless. O 0.79 m O 1.43 m O 1.03 m O 2.24 m
In the figure below, block 2 of mass m2 = 3.75 kg rests on a frictionless surface. It is attached to mass 1 (m1 = 2.50 kg) by a massless, stretchless string that passes over a frictionless pulley of radius R = 15.0 cm. When released from rest, block 2 moves to the right with an acceleration of 3.80 m/s2. What is the mass of the pulley? must draw FBDs
A thin rod with a length of 4.0 m and a mass of 4.2 kg is initially at rest. It is capable of spinning around a frictionless axle that goes through the top of the rod. A 2.5 kg mass of clay collides perfectly idealistically with the bottom of the rod. The clay was traveling perfectly horizontally with a speed of 12 m/s before the collision. How fast will the rod with the clay attached to it rotate around the axle in radians per second? The only external force on the clay/rod system come from the axle, which exerts no torque about itself.
