Answer:
Average net force, F = 15157.15 N
Step-by-step explanation:
It is given that,
The mass of the car and riders is,
![m=3* 10^3\ kg](https://img.qammunity.org/2020/formulas/physics/college/ypy2dwz87jz3gn9lpxb16rvzdnnjo9ac70.png)
Initial speed of the car, u = 0
Final speed of the car, v = 43.4 m/s
Time, t = 8.59 seconds
We need to find the average net force exerted on the car and riders by the magnets. It can be calculated using second law of motion as :
F = m a
![F=m((v-u)/(t))](https://img.qammunity.org/2020/formulas/physics/college/u17mw4pxfvkc2ndurp7p4zga0rde191039.png)
![F=3* 10^3\ kg* ((43.4\ m/s-0)/(8.59\ s))](https://img.qammunity.org/2020/formulas/physics/college/go3begxt91yu55l7g98qm07lvg10wgajhe.png)
F = 15157.15 N
So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.
