Ответ:
Average net force, F = 15157.15 N
Explanation:
It is given that,
The mass of the car and riders is,
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 = 15157.15 N
So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.

hello, i am papaguy.
i have found an answer to your question but use it as information.
information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.
best of luck!
