A force of 20 n acts upon a 5 kg block, calculate acceleration of the object

1. Newton's Second Law tells us how to calculate the acceleration if we know the force and the mass.

F = m a

We are interested in determining the acceleration, so we divide both sides of the equation by m to get F / m = a a = (20 N) / (5 kg) a = 4 N / kg = 4 (kg m / s2) / kg = 4 m / s 2
