Question

An object accelerates 8.2m/s2 when a force of 20.1N is applied to it. What is the mass of the object?

Answer 1

According to Newton's second law:

$a = F/m$ , where a -- acceleration, F -- force, m -- mass;

Find the mass of the object:

$m = F/a = 20.1/8.2 = 2.45 (kg)$

Answer: 2.45 kg -- the mass of the object.
