Question

A net force of 50 N is applied to an object, causing it to accelerate at 10 m/s². What is the mass of the object?

2 kg
5 kg
0.2 kg
500 kg

Answer 1

To find the mass of the object, we can use Newton's second law of motion, which states that \( F = m \cdot a \), where:

- \( F \) is the net force (in Newtons),
- \( m \) is the mass (in kilograms),
- \( a \) is the acceleration (in meters per second squared).

We are given:
- \( F = 50 \, \text{N} \)
- \( a = 10 \, \text{m/s}^2 \)

We can rearrange the formula to solve for mass \( m \):

\[
m = \frac{F}{a}
\]

Now, we can plug in the values:

\[
m = \frac{50 \, \text{N}}{10 \, \text{m/s}^2} = 5 \, \text{kg}
\]

The mass of the object is **5 kg**.
