Answer 2

Given:

mass of a cylinder m = 60 Kg

the radius of a cylinder r = 2 m

velocity v = 4m/s

To find:

the kinetic energy​ of a cylinder K.E. =?

Step-to-step-explanation:

• A cylinder of mass 30 Kg and radius of 2 meters is rolling on a table without sliding.
• The kinetic energy of a rolling cylinder is given by:

        $\displaystyle K.E. = \frac{1}{2}mv^2$

        where

        K.E.= kinetic energy of a rolling cylinder

        m = mass of a cylinder

         v = velocity

• Put the given values in the above equation to calculate the kinetic energy of a rolling cylinder.

         K.E. = 0.5 × 30 × 4 × 4

         K.E. = 240 J

• The kinetic energy of a cylinder is 240 J.
