Answer:
Average net force, F = 15157.15 N
Explanation:
It is given that,
The mass of the car and riders is, [tex]m=3\times 10^3\ kg[/tex]
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
[tex]F=m(\dfrac{v-u}{t})[/tex]
[tex]F=3\times 10^3\ kg\times (\dfrac{43.4\ m/s-0}{8.59\ s})[/tex]
F = 15157.15 N
So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.
