2.3.5. [Level 1] The lower portion of a fire ladder ( A )
rotates about its hinge O at ® = 0.05 rad/s and ö = 0.04 rad/s?
The upper portion extends out from the lower portion such
that c = 0.4 m/s and * = 0.1 m/s. Determine the velocity
and acceleration of B with respect to e,, e, as well as i, j for
0 = I rad and c = 2 m.
