- In an old-fashioned amusement park ride, passengers stand inside a 4.6-m-diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. A sign next to the entrance says "No children under 30 kg allowed." What is the minimum angular speed, in rpmrpm, for which the ride is safe?A packing crate with mass 80.0 kg is at rest on a horizontal, frictionless surface. At t = 0 a net horizontal force in the +x-direction is applied to the crate. The force has a constant value of 80.0 N for 12.0 s and then decreases linearly with time so it becomes zero after an additional 6.00 s. What is the final speed of the crate, 18.0 s after the force was first applied?I kg is initially A wedge of mass driven up a frictionless ramp by a horizontal force F = 50 N due to a small attached rocket.

Give the direction as an angle from the r-axis. c) If the car has rubber tires and the track is concrete, at what time does the car begin to slide out of the circle?In the figure, a car is driven at constant speed over a circular hill and then into a circular valley with the same radius. At the top of the hill, the normal force on the driver from the car seat is 0. The driver's mass is 74.0 kg. What is the magnitude of the normal force on the driver from the seat when the car passes through the bottom of the valley?The drawing shows a baggage carousel at an airport. Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle ((r = 8.90 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.640, and the angle 0 in the drawing is 5.90°. How much time is required for your suitcase to go around once? Assumme that the static friction between the suitcase and the carousel is at its maximum.
