Chapter 12: Q. 35 (page 331)
35. II An 8.0-cm-diameter, 400g solid sphere is released from rest at the top of a 2.1-m-long, incline. It rolls, without slipping, to the bottom.
a. What is the sphere's angular velocity at the bottom of the incline?
b. What fraction of its kinetic energy is rotational?

An 800 g steel plate has the shape of the isosceles triangle shown in FIGURE P12.50. What are the x- and y-coordinates of the center of mass?
Hint: Divide the triangle into vertical strips of width dx, then relate the mass dm of a strip at position x to the values of x and dx.
A 1.0 kg ball and a 2.0kg ball are connected by a 1.0 m rigid, massless rod. The rod is rotating about its center of mass at 20 rpm. What net torque will bring the balls to a halt in 5.0 s?
A thin, 100g disk with a diameter of 8.0 cm rotates about an axis through its center with 0.15 J of kinetic energy. What is the speed of a point on the rim?
Your engineering team has been assigned the task of measuring the properties of a new jet-engine turbine. You’ve previously determined that the turbine’s moment of inertia is 2.6 kg m2. The next job is to measure the frictional torque of the bearings. Your plan is to run the turbine up to a predetermined rotation speed, cut the power, and time how long it takes the turbine to reduce its rotation speed by 50,. Your data are given in the table. Draw an appropriate graph of the data and, from the slope of the best-fit line, determine the frictional torque.
A solid sphere of radius R is placed at a height of 30 cm on a slope. It is released and rolls, without slipping, to the bottom. From what height should a circular hoop of radius be released on the same slope in order to equal the sphere's speed at the bottom?
