Question

A model rocket accelerates at 15.3 m/s2 with a force of 44 N.

Calculate the mass of the rocket. Round your answer to the nearest tenth of a kg.

The mass of the rocket is
kg.

Answer 1

To find the mass of the rocket, you can use Newton's second law of motion, which states that \( F = m \cdot a \), where \( F \) is the force, \( m \) is the mass, and \( a \) is the acceleration.

Given:
- Force \( F = 44 \, \text{N} \)
- Acceleration \( a = 15.3 \, \text{m/s}^2 \)

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

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

Substituting the values in:

\[
m = \frac{44 \, \text{N}}{15.3 \, \text{m/s}^2}
\]

Now, calculate the mass:

\[
m \approx \frac{44}{15.3} \approx 2.867
\]

Rounding to the nearest tenth:

\[
m \approx 2.9 \, \text{kg}
\]

Thus, the mass of the rocket is **2.9 kg**.
