question 22 of 29
a car accelerates at a rate of 8.8 m/s² with a force from the tires of 11,968 n. what is the mass of the car?

a. 2270 kg
b. 1360 kg
c. 1800 kg
d. 2140 kg

Explanation:

Step1: Recall Newton's second - law formula

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

Step2: Rearrange the formula for mass

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

Step3: Substitute given values

Given $F = 11968\ N$ and $a=8.8\ m/s^{2}$, then $m=\frac{11968}{8.8}$.

Step4: Calculate the mass

$m = 1360\ kg$

Answer:

B. 1360 kg
