How fast should a man of mass 60kg run so that his kinetic energy is 750 J ?

Explanation

To find out how fast a man of mass 60 kg should run so that his kinetic energy is 750 J, we can use the formula for kinetic energy:

### Step 1: Write down the formula for kinetic energy.
The formula for kinetic energy (KE) is given by:
\[ KE = \frac{1}{2} m v^2 \]
where:
