In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 42 m/s (around 90 mi/h) in a time of 7.3 s. The mass of the car and riders is 5700 kg. Find the average net force exerted on the car and riders by the magnets.

1 answer

a = (V-Vo)/t = (42-0)/7.3 = 5.75 m/s^2.

F = m*a = 5700 * 5.75 = 32,795 N.
