Multiple-concept example 11 provides some pertinent back- ground for this problem. a pendulum is constructed from a thin, rigid, and uniform rod with a small sphere attached to the end opposite the pivot. this arrangement is a good approximation to a simple pendulum (period 0.66 s), because the mass of the sphere (lead) is much greater than the mass of the rod (aluminum). when the sphere is removed, the pendulum is no longer a simple pendulum, but is then a physical pendulum. what is the period of the physical pendulum?

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
