In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 36 m/s (around 80 mi/h) in a time of 5.5 s. The mass of the car and riders is 4900 kg. Find the average net force exerted on the car and riders by the magnets.
F= m*a = m*(v-u)/t
v is the velocity after time t(5.5s)
u is the initial velocity = 0
Plug in the values to find the av. net force F
