SP3. In the park, several children with a total mass of 240 kg areriding on a merry-go-round that has a rotational inertia of1500 kg-m² and a radius of 2.2 m. The average distance ofthe children from the axle of the merry-go-round is 2.0 minitially, since they are all riding near the edge. a. What is the rotational inertia of the children about theaxle of the merry-go-round? What is the total rotationalinertia of the children and the merry-go-round?b. The children now move inward toward the center of themerry-go-round so that their average distance from theaxle is 0.5 m. What is the new rotational inertia for thesystem?c. If the initial rotational velocity of the merry-go-roundwas 1.2 rad/s, what is the rotational velocity after thechildren move in toward the center, assuming that thefrictional torque can be ignored? (Use conservation ofangular momentum.)d. Is the merry-go-round rotationally accelerated duringthis process? If so, where does the accelerating torquecome from?

Keratinocytes are the most common cells in the skins outer layer. As these approximately circular cells migrate across a wound during the healing process, they roll in a way that reduces the frictional forces impeding their motion. (a) Given a cell body diameter of 1.00 105 m (10 m), what minimum angular speed would be required to produce the observed linear speed of 1.67 107 m/s (10 m/min)? (b) How many complete revolutions would be required for the cell to roll a distance of 5.00 103 m? (Because of slipping as the cells roll, averages of observed angular speeds and the number of complete revolutions are about three times these minimum values.)
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 2.00 cm and is rolled by the beetle at 6.25 cm/s. (a) What is the rolling balls angular speed? (b) How many full rotations are required if the beetle rolls the ball a distance of 1.00 m?

The ability of the human eye to rapidly rotate was studied using contact lenses fitted with accelerometers. While a subject, whose eyeball has radius 1.25 cm, watches a moving object her eyeball rotates through 20.0° in a time interval of 69.6 ms. a. What is the magnitude of the average angular velocity of the eye? asnwer in rad/s b. Assume that the eye starts at rest, rotates with a constant angular acceleration during the first half of the interval, and then the rotation slows with a constant angular acceleration during the second half until it comes to rest. What is the magnitude of the angular acceleration of the eye? answer in rad/s^2 c. What tangential acceleration would the contact-lens accelerometers record in this case? answer in m/s^2
