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 = 8.60 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.520, and the angle θ in the drawing is 8.54°. How much time, in seconds, is required for your suitcase to go around once? Assume that the static friction between the suitcase and the carousel is at its maximum.

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 = 12.0 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.840, and the angle 0 in the drawing is 12.9°. 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. Number MO Units

A skateboarder is attempting to make a circular arc of radius r = 11 m in a parking lot. The total mass of the skateboard and skateboarder is m = 86 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.59 . He speeds up very slightly and begins to slide. The coefficient of kinetic friction is μk = 0.21. What is the new magnitude of his radial acceleration in m/s2?

In deep space, an astronaut is whipping a heavy tool around in a circle by a taut cable. The cable is 1 meter long (from the astronaut's fist to the tool), and the tool makes a full trip around the circle in half a second as it moves with constant speed. The mass of the tool is 10 kg. What is the tension in the cable?

Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B contains lead shot. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is ms. When the speed of the turntable is gradually increased,

A leashed chihuahua is held by its owner in a park. The dog is walking and undergoes a displacementi = (0. 5 m)î + (1.8 m)j. If the tension in the leash is T = (-10.0î + 7.8ĵ)N. What is the angle between the two vectors?

A chandelier hangs h = 0.74 m down from two chains of equal length. The chains are separated from one another by a length L = 0.85 m at the ceiling. The chandelier has a mass of m = 28 kg. What is the angle, θ in degrees, between one of the chains and the vertical where it contacts the chandelier?

The physics of circular motion sets an upper limit to the speed of human walking. (If you need to go faster, your gait changes from a walk to a run.) If you take a few steps and watch what's happening, you'll see that your body pivots in circular motion over your forward foot as you bring your rear foot forward for the next step. As you do so, the normal force of the ground on your foot decreases and your body tries to "lift off" from the ground. A. A person's center of mass is very near the hips, at the top of the legs. Model a person as a particle of mass m at the top of a leg of length L.   Find an expression for the person's maximum walking speed vmax  Express your answer in terms of the variables L and appropriate constants.   b.)Evaluate your expression for the maximum walking speed of a 70 kg person with a typical leg length of 70 cm . Give your answer in m/s.   c.) Give your answer in mph.

A 5.0 g coin is placed 15 cm from the center of a turntable. The coin has static and kinetic coefficients of friction with the turntable surface of μs = 0.70 and μk = 0.50. The turntable very slowly speeds up. What is the frequency of the rotation of the turntable expressed in revolutions per minute when the coin slides off? Express your answer in revolutions per minute.

A jet airplane is in level flight. The mass of the airplane is ?=8990 kg.m=8990 kg. The airplane travels at a constant speed around a circular path of radius ?=9.33 miR=9.33 mi and makes one revolution every ?=0.123 h.T=0.123 h. Given that the lift force acts perpendicularly upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane?
