rrent Attempt in Progress In an automatic clothes drier, a hollow cylinder moves the clothes on a vertical circle (radius r=0.516 m), as the drawing shows. The appliance is designed so that the clothes tumble gently as they dry. This means that when a piece of clothing reaches an angle of 0 above the horizontal, it loses contact with the wall of the cylinder and falls onto the clothes below. How many revolutions per second should the cylinder make in order that the clothes lose contact with the wall when 8 = 57.0°? 2 Number i eTextbook and Media Save for Later Units Weducation.wiley.com/was/ui/v2/assessment-player/index.html?launchid=87c04f9d-f34c-4936-9853-14158c3e5e24# Attempts: 1 of 5 used Submit Answer

You have a horizontal grindstone (a disk) that is 87 kg, has a 0.31 m radius, is turning at 94 rpm (in the positive direction), and you press a steel axe against the edge with a force of 23 N in the radial direction. The kinetic coefficient of friction between steel and stone is 0.20. What is the number of turns, N, that the stone will make before coming to rest?

A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.7s before coming to rest.How many revolutions did the centrifuge complete after being turned off?Δθ= (?) rev

A centrifuge in a biochemistry laboratory rotates at an angular speed of 3,650 rev/min, clockwise (when viewed from above). When switched off, it rotates through 48.0 revolutions before coming to rest. Assuming it is constant, what is the magnitude of angular acceleration (in rad/s²)? rad/s² What is the direction of the angular acceleration (again, when viewed from above)? clockwise оо counterclockwise The magnitude is zero.

An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.200 rev/s. The magnitude of the angular acceleration is 0.881 rev/s². Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.800 m. Part E Calculate the magnitude ar of the radial (or centripetal) acceleration of the point at the end of the fan blade. ▾ View Available Hint(s) Hint 1.

In an automatic clothes drier, a hollow cylinder moves the clothes on a vertical circle (radius r = 0.519 m), as the drawing shows. The appliance is designed so that the clothes tumble gently as they dry. This means that when a piece of clothing reaches an angle of 0 above the horizontal, it loses contact with the wall of the cylinder and falls onto the clothes below. How many revolutions per second should the cylinder make in order that the clothes lose contact with the wall when 0 = 64.0°? Number Units

Imagine If A skateboarder is attempting to make a circular arc of radius r = 19 m in a parking lot. We know the total mass of the skateboard and skateboarder is m = 95 kg. If the coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.66 . A) Now what is the maximum speed, in meters per second, he can travel through the arc without slipping?

Question 4. A single bead can slide without friction on a vertical hoop of radius r. The hoop rotates about its vertical axis and makes one complete revolution in T seconds. The position of the bead is described by the angle 0. At what 0 > 0 can the bead stay stationary while the hoop rotates? r
