Numerical problems Calculate
Speed of a 1 kg mass having KE. equal to 1 J.

Explanation

To calculate the speed of a 1 kg mass having kinetic energy equal to 1 joule, we can use the formula for kinetic energy (KE):

### Step-by-Step Solution:

1. **Write down the formula for kinetic energy**:
\[ KE = \frac{1}{2} m v^2 \]
