A wheel with a weight of 395 N comes off a moving truck and rolls without slipping along a highway. At the bottom of a hill it is rotating at an angular velocity of 26.1 rad/s . The radius of the wheel is 0.651 m and its moment of inertia about its rotation axis is 0.800 MR2. Friction does work on the wheel as it rolls up the hill to a stop, at a height of h above the bottom of the hill; this work has a magnitude of 3458 J .

Calculate h.

Use 9.81 m/s2 for the acceleration due to gravity.

1. A cylindrical wooden log rolls without slipping down a small ramp. The log has a radius of 16 cm, a length of 2.5 m, and a mass of 130 kg. The log starts from rest near the top of the ramp. When the log reaches the bottom of the ramp, it is rolling at a linear speed of 2.3 m/s. a.) Assuming that the log is a perfect cylinder of uniform density, find the log’s moment of inertia (about...
