From Newton’s second law of motion, the value of the force is calculated by multiplying the mass and the acceleration as,
<span> F = mass x acceleration</span>
If we substitute the known values into the equation,
<span> 16 N = 80 kg x acceleration</span>
<span> Acceleration = 0.2 m/s<span>2</span></span>
