In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 45.7 m/s in a time of 7.17 s. The mass of the car and riders is 6.15 × 103 kg. Find the average net force exerted on the car and riders by the magnets.
Homework Answers
vf = vi + at
45.7 m/s =
0 + a(7.17 s)
a = 6.37
m/s2
Favg = ma
= (6.15 × 103 kg)(6.37 m/s2)
= 39198.74 N

On the ride "Spindletop" at an amusement Park, people stood against the inner wall of a hollow vertical cylinder with radius 2.5 m. The cylinder begins to turn, the rider, wall, and the floor moves in unison. When the cylinder reaches a constant speed of 7.2 m/s, the floor on which the rider is drops off. The rider does not fall with it but instead is pinned against the wall. (a) What is the minimum coefficient of static friction? (b)...

In an amusement park ride called The Roundup, passengers stand inside a 17.0 m -diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane. Suppose the ring rotates once every 4.50 s . If a rider's mass is 56.0 kg , with how much force does the ring push on her at the top of the ride? Suppose the ring rotates once every 4.50 s . If a rider's mass is 56.0 kg ,...

The Gravitron is an amusement park ride in which riders stand against the inner wall of a large spinning steel cylinder. At some point, the floor of the Graviton drops out, instilling the fear in riders that they will fall a great height. However, the spinning motion of the Gravitron allows them to remain safely inside the ride. Most Gravitrons feature vertical walls, but the example shown in the figure has tapered walls of 25.7o. According to knowledgeable sources, the...

A pair of bumper cars in an amusement park ride collide elastically as one approaches the other directly from the rear, as seen in part (a) of the figure below. ((a) before collision, (b) after collision) One has a mass of m1 = 441 kg and the other m2 = 562 kg, owing to differences in passenger mass. If the lighter one approaches at v1 = 4.30 m/s and the other is moving at v2 = 3.70 m/s, calculate the...
