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.

Explanation:

Step1: Recall Newton's second law

Newton's second law is $F = ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration. Rearrange to solve for mass: $m = \frac{F}{a}$

Step2: Substitute given values

Substitute $F = 44\ \text{N}$ and $a = 15.3\ \text{m/s}^2$ into the formula:
$m = \frac{44}{15.3}$

Step3: Calculate and round the value

Perform the division and round to the nearest tenth:
$m \approx 2.9$

Answer:

2.9
