A point on the rim of a rotating flywheels changes its speed from 1.5 m/sec. to 9.0 m/sec. while it moves 60m. If the radius of the wheel is 1.0m, what are the normal, tangential and absolute accelerations at the instant when the speed is 6.0 m/sec.?

A pulley having a 5.0-cm radius is turning at 30 rev/s about its central axis. It is slowed down uniformly to 20 rev/s in 2.0 s. Calculate the angular acceleration of the pulley, the angle through which it turns in this time, the length of belt it winds in that same time.

An ultracentrifuge accelerates from rest to 9.97×10^5 rpm in 1.51 min. What is its angular acceleration in radians per second squared? What is the tangential acceleration of a point 9.10 cm from the axis of rotation? What is the radial acceleration in meters per second squared and in multiples of ? of this point at full revolutions per minute?

A wheel of a radius 5.02 m rotates at a uniform speed. If a point on the rim of the wheel has a centripetal acceleration of 4.00 m/s2, what is the point’s tangential speed?

A Google search revealed that the disc in a CD player spins at between 200 and 500 revolutions per minute (RPM) depending upon which area of the disc is being read or played. (a) How many radians per second are equivalent to 200 RPM? (b) By pressing and holding the fast-forward button, the CD player could quickly increase its speed from 200 RPM to 448 RPM in just 0.75 seconds. What was the angular acceleration (α) of the CD in units of radians per secondsquared as it sped up from 200 to 448 RPM?

An ultracentrifuge accelerates from rest to 109700 rpm in 2.05 min. ω = 109700 rpmt = 2.05 minl = 9.4 cma. What is its angular acceleration in rad/s2? α =b. What is the tangential acceleration of a point 9.4 cm from the axis of rotation in m/s2? at =c. What is the centripetal acceleration in multiples of g of this point at full speed? a/g =

. A centrifuge will be used to give astronauts a gravity “spin-up” for one hour per day while on Mars. If thecentrifuge begins at rest and increases to 18 revolutions per minute. Find (a) the angular acceleration and (b)the final angular velocity in rpm.

The royal antelope of western Africa has an average mass of only 2.5 kg. Suppose thisantelope runs in a circle with a radius of 35.0 m. If a force of 8.8 N maintains this circularmotion, what is the antelope’s tangential speed?

A Lazy Susan (turning tabletop) has radius 0.750 m. An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s. What is the value of the apple's tangential acceleration at 3.00 second in m/s²? Your Answer: Answer A Question 26 (4 points) staks question A Lazy Susan (turning tabletop) has radius 0.750 m.
