Question

a 10 kg cart is pushed with a net force of 40 n. what is its acceleration?
40 m/s²
2 m/s²
4 m/s²
10 m/s²

Explanation:

Step1: Recall Newton's second - law

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. We need to solve for $a$.

Step2: Rearrange the formula for $a$

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

Step3: Substitute given values

$F = 40\ N$ and $m = 10\ kg$, so $a=\frac{40\ N}{10\ kg}=4\ m/s^{2}$

Answer:

C. $4\ m/s^{2}$
