A disc of radius m and mass kg rolls on a horizontal floor. Its centre of mass has speed of cm/s. How much work is needed to stop it?
J
kJ

J
To solve this problem, we need to calculate the total kinetic energy of the disc and determine the work required to stop it.The total kinetic energy of a rolling object is the sum of its translational and rotational kinetic energy.Given:• Radius of the disc m• Mass of the disc
