Question

An object accelerates 2 m/s2 when an unknown force of 20 N is applied to it. What was the mass of the object?

Answer 1

Answer:

10 kg

Explanation:

The mass of an object given only the force acting on it and it's acceleration can be found by using the formula

$m = \frac{f}{a}$

f is the force in N

a is the acceleration in m/s²

We have

$m = \frac{20}{2} = 10$

We have the final answer as

10 kg
