Sagot :
Answer:
The average force that brings the car to rest is 175000N
Explanation:The mass of the car, m = 1000 kg
Initial speed, u = 14 m/s
Final speed, v = 0 m/s (Since the car comes to a stop)
The time taken, t = 8 x 10^-2 s
The average force is calculated as:
[tex]\begin{gathered} F=\frac{m(u-v)}{t} \\ F=\frac{1000(14-0)}{8\times10^{-2}} \\ F=\frac{14000}{0.08} \\ F=175000N \end{gathered}[/tex]The average force that brings the car to rest is 175000N
