Question

newtons laws practice
what is the mass of a truck if a force of 14,000 n is applied causing it to accelerate at a rate of 5 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 $m$.

Step2: Rearrange the formula for mass

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

Step3: Substitute the given values

$F = 14000\ N$, $a = 5\ m/s^{2}$, so $m=\frac{14000}{5}$

Step4: Calculate the mass

$m = 2800\ kg$

Answer:

$2800\ kg$
