Problem 23

How does increasing the moment of inertia affect how easily an object rotates?

Problem 24

Generalize How will doubling the mass of an object affect its moment of inertia?

Problem 28

As a car travels along a road, the speed of the tops of its wheels is \(46 \mathrm{~m} / \mathrm{s}\). What is the speed of the car and its occupants?

Problem 29

Calculate A basketball has a radius of \(0.12 \mathrm{~m}\) and a mass of \(0.57 \mathrm{~kg}\). Assuming the ball to be a hollow sphere, what is its moment of inertia?

Problem 30

Calculate A chef spins a disk of pizza dough over her head, giving it an angular speed of \(7.2 \mathrm{rad} / \mathrm{s}\). If the moment of inertia of the pizza dough is \(6.3 \times 10^{-6} \mathrm{~kg} \cdot \mathrm{m}^{2}\), what is its rotational kinetic energy? (Assume that the disk of dough is uniform.)
