You have been charged with operating "the gravitron" at the carnival. In this popular amusement ride, the entire ride spins with nauseous fairgoers leaning against the outside wall. When the requisite speed is reached, the floor opens up with the riders (red box in diagram below) pinned against the wall. You know that the ride has radius of R = 4.8 m (from center axis to rider's position), a wall angle θ = 25 reclined from vertical, and a coefficient of static friction μs = 0.24 between the rider and the wall.
What minimum rotation speed should you reach before dropping the floor?
A 2000 Hz sound wave passes through a wall with two narrow openings 30 cm apart. If sound travels on average 345 m/s, What is the angle of the first order maximum
an unstable particle at rest breaks up into two fragments of unequal mass. the mass of the lighter fragment is equal to
A child of mass 40.0 kilogram is sitting on a horizontal seesaw at a distance of 1.9 meter from the supporting axis. Evaluate the magnitude of the torque about the axis due to the weight of the child
The weight of a 1200 kgcar is supported equally by the four tires, which are inflated to the same gauge pressure. What gauge pressure is required
a cosmic ray particle travels directly over a soccer field from one goal line to the other at a speed of 0.522c. if the
Two blocks of weights 45.0 and 83.0 N are connected by as massless string and slide down an inclined plane making an angle of 31.0 deg. to the horizontal. find the magnitude of the lighter block's acceleration
A 35.5 kg girl and a 58.0 kg boy are on the surface of a frozen lake, 12.5 m apart. Using a rope, the girl exerts a horizontal 4.60 N force on the boy, pulling him toward her. Draw a free body diagram. Compute the magnitude of the girl's acceleration
A refracting telescope is used to view the Moon (diameter 3480 km, distance from Earth 385,000 km). What should be the distance between the lenses
If you were to take a 60.0 cm long steel bar, and heated it to the point that it would try to expand by 0.50 mm, What is the pressure you would need to apply
A yo-yo with a mass of 0.302 kilogram is swung in a vertical circle of radius 0.880 meter. Obtain the tension in the springtide to the yo-yo when it is at the top of the circle
Two particles each have a mass of 6.00 g. One has a charge of -1.5 µC and the other has a charge of +1.5 µC. They are initially held at rest at a distance of 0.80 m apart. Both are then released and accelerate toward each other. How fast is each part..
You are the operator of a 15,000 V rms, 60 Hz electrical sub-statin. When you get to work one day, you see that the station is delivering 6.0 MW of power with a power factor of .90. how much power will the station then be delivering
