Determine the indicated terms used in the velocity and acceleration formulas.

Answers:

r =	__ in.	θ =	___ °
r˙ =	__in./sec	θ˙ =	____ rad/s
r¨ =	___ in./sec²	θ¨ =	____rad/s²

Consider the portion of an excavator shown. At the instant under consideration, the hydraulic cylinder is extending at a rate of 5
in./sec, which is decreasing at the rate of 2 in./sec every second. Simultaneously, the cylinder is rotating about a horizontal axis
through O at a constant rate of 13 deg/sec. Determine the velocity v and acceleration a of the clevis attachment at B.
