A horizontal `9 kg` merry-go-round is a solid disk of radius `1.50 m` and is started from rest by a constant horizontal force of `50.0 N` applied tangentially to the edge of the disk. The kinetic energy of the disk after `3.00 s` is.

A circular disk of radius 0.010 m rotates with a constant angular speed of 5.0 rev/s. What is the acceleration of a point on the edge of the disk?

Figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.00 cm and a mass of 20.0 grams and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t = 1.25 s the disk has an angular velocity of 250 rad/s counterclockwise. Force vecF_(1) has a magnitude of 0.100 N. What is magnitude F_(2) ?

An object of mass 50 kg is moving in a horizontal circle of radius 8 m. If the centripetal force is 40 N, then the kinetic energy of the object will be

A solid sphere of radius R is resting on a smooth horizontal surface. A constant force F is applied at a height h from the bottom. Choose the correct alternative.

A 1.0 kg wheel in the form of a solid disk rolls along a horizontal surface with a speed of 6.0 m/s. What is the total kinetic energy of the wheel?

A girl of mass M stands on the rim of a frictionless merry-go-round of radius R and rotational inertia I that is not moving. She throws a rock of mass m horizontally in a direction that is tangent to the outer edge of the merry-go-round. The speed of the rock, relative to the rock. relative to the ground, is v . After, the linear speed of the girl is. .

A 1.0-kg wheel in the form of a solid disk rolls along a horizontal surface with a speed of 6.0 m//s . What is the total kinetic energy of the wheel?
