The world's tallest Ferris wheel is the High Roller in Las Vegas, NV. It has a radius of about 79 m If the ride time is 8 minutes (480 s), then how many revolutions does the wheel make and how many radians has it rotated?

An ultracentrifuge accelerates uniformly from rest to 100,000 rpm in 2.0 min. If this ultracentrifuge accelerates 4.0 seconds starting from rest, what is the magnitude of the centripetal acceleration in unit of gravitational acceleration g for your sample sitting at 4.0 cm from the center axis? Use g = 9.8 m/s2. Hint: compute the centripetal acceleration in unit of m/s2 first, then divided by g will be your answer. For example, if your centripetal acceleration is 19.6 m/s2, your answer measured in unit of g is 2.0.

An automobile tire is rated to last 50000 miles.to an order magnitude, through how many revolutions will it turn ?

An object travels in a circular path. It takes 2.4 seconds to complete each rotation. If the radius of the circle is 6.3 m, what is the object's average linear speed?

A disk of radius 2.25 m rotates about its axis. Points on the rim of the disk undergo tangential acceleration of magnitude 1.81 m/s?. At a particular time, the rim has a tangential speed of 1.67 m/s. At a time 0.867 s later, what is the tangential speed v of a point on the rim, the magnitude of the point's radial acceleration a,, and the magnitude of its total acceleration Arot? U = m/s ar = m/s? Atot = m/s?

A Ferris wheel has a radius of 42.4 feet. The bottom of the Ferris wheel sits 0.8 feet above the ground. You board the Ferris wheel at the 6 o'clock position and rotate counter- clockwise. a. Define a function, f that gives your height above the ground (in feet) in terms of the angle of rotation (measured in radians) you have swept out from the 6 o'clock position, a f(a)-42.4sin(a)+43.2 Preview b. Define a function, g, that gives your height above the ground (in feet) in terms of the number of feet you have rotated counter-clockwise from the 6 o'clock position, s. g(s)=43.2+42.2sin(s/42.4) Preview

A ceiling fan is turned on and reaches an angular speed of 111 rev/min in 23 s. It is then turned off and coasts to a stop in 47 s. In the [t1+t2] s of rotation, through how many revolutions did the fan turn?

A centrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. When switched off, it rotates through 54.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.
