Answer: The ladder of the fire truck rotates around the z
Chapter 20, Problem 20-3(choose chapter or problem)
The ladder of the fire truck rotates around the z axis with an angular velocity \(\omega_{1}=0.15 \ \mathrm{rad} / \mathrm{s}\), which is increasing at \(0.8 \ \mathrm{rad} / \mathrm{s}^{2}\). At the same instant it is rotating upward at a constant rate \(\omega_{2}=0.6 \ \mathrm{rad} / \mathrm{s}\). Determine the velocity and acceleration of point A located at the top of the ladder at this instant.
