The kinetic energy of a rolling solid cylinder of mass `4kg` about it axis of rotation is `20kgm^(2)s^(-2)`. Calculate the velocity with which it is moving.

Explanation

To solve the problem, we need to calculate the velocity of a rolling solid cylinder given its mass and kinetic energy. The total kinetic energy of a rolling object is the sum of its translational and rotational kinetic energy.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Mass of the cylinder, \( m = 4 \, \text{kg} \)
- Total kinetic energy, \( KE = 20 \, \text{kg m}^2/\text{s}^2 \)
