Correct answer would be d
Answer:
26.822 m/s
Explanation:
60 mi/hr * 5280 ft/mile * 1 hr / 3600 sec * 12 in / foot * 1 meter / 39.37 in = <u>26.822 m/s</u>
Answer:
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.
