For a rotating object rotating in a circle with constant angular speed, the ONLY force acting on the object is a centripetal force keeping it in a circular orbit.

A uniform 39.0-N board supports two children weighing 510 N and 350 N. If the support is at the center of the board and the 510-N child is 1.4 m from its center to the left of the support, how far is the 350-N child from the center if the system is balanced? Two significant digits.

A torque of 12.0 N ∙ m is applied to a solid, uniform disk of radius 0.700 m. If the disk accelerates at 1.80 rad/s2 what is the mass of the disk? Three significant digits.

A solid disk has a 1.5 m diameter and a mass of 250 kg. A motor spins up the disk with a constant torque of 50 .  How long in seconds does it take the disk to reach top angular speed of 1200 rpm?

If a circular, disk-type object is merely sliding down a steep hill, it has more total kinetic energy than if it were rolling.

How much momentum does a 2.5 kg particle have moving with a speed of 10.0 m’s?
