A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to \(5.20 m / s\) in \(0.832 s\). What is the average total force experienced by a \(70 kg\) passenger in the car during the time the car accelerates?
A. \(364 N\) B. \(43.5 N\) C. \(437.5 N\) D. \(4375 N\)
Correct Answer: C
Explanation
Average force experienced $$ \begin{aligned} &f=m \frac{v-u}{t} \\ &f=\frac{70 \times(5.20-0)}{0.832} \\ &f=437.5 N \end{aligned} $$
