Question

In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 48.7 m/s in a time of 8.51 s. The mass of the car and riders is 9.18 × 103 kg. Find the average net force exerted on the car and riders by the magnets. In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 48.7 m/s in a time of 8.51 s. The mass of the car and riders is 9.18 × 103 kg. Find the average net force exerted on the car and riders by the magnets.

Explanation / Answer

Vo = initial speed = 0 m/s

Vf = final speed = 48.7 m/s

t = time = 8.51 s

acceleration is given as

a = (Vf - Vo)/t = (48.7 - 0)/8.51 = 5.72 m/s

m = mass = 9180 kg

average net force is given as

F = ma

F = (9180) (5.72) = 52509.6 N
