The dung beetle is known as one of the strongest animals for its size, often forming balls of dung up to 10 times their own mass and rolling them to locations where they can be buried and stored as food. A typical dung ball formed by the species K. nigroaeneus has a radius of 2.05 cm and is rolled by the beetle at 6.05 cm/s. HINT (a) What is the rolling ball's angular speed (in rad/s)? rad/s (b) How many full revolutions are required if the beetle rolls the ball a distance of 2.90 m? rev

A computer hard disk 8.0 cm in diameter is initially at rest. A small dot is painted on the edge of the disk. The disk accelerates at 700 rad/s^2 for 1/2s, then coasts at a steady angular velocity for another 1/2s. What is the speed of the dot at t= 1.0 s? Through how many revolutions has it turned?

A centrifuge in a medical laboratory rotates at an angular speed of 3,750 rev/min. When switched off, it rotates through 48.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

Human centrifuges are used to train military pilots and astronauts in preparation for high-g maneuvers. A trained, fit person wearing a g-suit can withstand accelerations up to about 9g (88.2 m/s2) without losing consciousness. (A) If a human centrifuge has a radius of 4.29 m, what angular speed (in rad/s) results in a centripetal acceleration of 9g? rad/s ?   (B) What linear speed (in m/s) would a person in the centrifuge have at this acceleration? m/s

Starting from rest, a wheel with a radius of 0.55 m begins to roll across the ground in a straight line under a constant angular acceleration of 4.05 rad/s2. What is the speed of the wheel in m/s after it has rotated through 17 full revolutions

A centrifuge in a medical laboratory rotates at an angular speed of 3,700 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 flywheel slows from 517.7 rev/min down to 364.9 rev/min while spinning through 44.4 revolutions. What is the angular acceleration of the flywheel (in rad/s/s)? Assume that the flywheel slows down at a constant rate.

A centrifuge in a medical laboratory rotates at an angular speed of 3,650 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 boy rides his bicycle 2.00 km. The wheels have radius 30.0 cm. What is the total angle the tires rotate through during his trip?

A ferris wheel begins at rest. During the first part of the journey, the ferris wheel accelerates through 4 rotations at a rate of 0.0500 rad/s2. During the second part of the journey, the ferris wheel then remains at its top speed for 14 rotations. Finally, during the third part of the journey, the ferris wheel slows down to rest over 3 rotations. What is the ferris wheel's top angular speed? How long does it take for the ferris wheel to accelerate from rest up to its top speed? How long the ferris wheel remain at its top speed for? How long does it take for the ferris wheel to slow down from top speed to rest?
