Question

What is mass if force is 45 N and acceleration is 39 m/s/s?

Answer 1

Answer:

The answer is 1.15 kg

Step-by-step explanation:

To find the mass of an object given it's acceleration and the force acting on it we use the formula

$mass = \frac{force}{acceleration}$

From the question

force = 45 N

acceleration = 39 m/s²

We have

$force = \frac{45}{39} = \frac{15}{13} \\ = 1.153846...$

We have the final answer as

1.15 kg
