Answer

Explanation:

Step1: Recall Newton's second - law formula

$F = ma$, where $F$ is the net - force, $m$ is the mass, and $a$ is the acceleration.

Step2: Calculate the net - force for Car 1

Given $m_1=1540\ kg$ and $a = 90\ m/s^2$. Using $F = ma$, we have $F_1=m_1a=1540\times90 = 138600\ N$.

Step3: Calculate the net - force for Car 2

Given $m_2 = 1428\ kg$ and $a = 90\ m/s^2$. Using $F = ma$, we have $F_2=m_2a=1428\times90=128520\ N$.

Step4: Compare the net - forces

Since $138600\ N>128520\ N$, Car 1 has a greater net - force.

Answer:

D. Car 1, 138600 N
