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?

When you start your record player, a ladybug is sitting on the edge of the record, 15 cm from the center. The record, initially at rest at t=0, experiences a constant angular acceleration of 0.698 rad/s for 5 seconds.  What is the magnitude of the centripetal acceleration of the ladybug at the moment t = 5 s?

A centrifuge in a medical laboratory rotates at an angular speed of 3,800 rev/min. When switched off, it rotates through 52.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

A wheel 2 m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4 rad/s2. The wheel starts at rest at t =0, and the radius vector of point P on the rim makes an angle of 57.3o with the horizontal at this time. At t=2s, find the angular speed of the wheel

The hard disk drive in a computer spins at a rate of 7.20 x 10^3 rpm. If the disk has a radius of 8.26 cm, what is the tangential speed of the outer edge of the disk?

An astronaut is inside a centrifuge that has a radius of 10 m. The astronaut starts from rest and experiences a constant angular acceleration for 10 seconds. After the 10 seconds, the astronaut is experiencing 10g, meaning that the centripetal acceleration is a. 98 . The angular displacement of the astronaut during the 10 seconds was rad.

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.

What is the value of the apple's centripetal acceleration at the 3.00 second in m/s²?

A centrifuge in a medical laboratory rotates at an angular speed of 3,550 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.

The period of a stone swung in a horizontal circle on a 2.50-m radius is 1.20 s. (a) What is its angular velocity in rad/s? (b) What is its linear speed in m/s? (c) What is its radial acceleration in m/s2?
