Example $20\mathrm{.}4$

A motor and attached rod $AB$ have the angular motions shown in Fig. $20-12.$ A collar

Figure $20-12$ C on the rod is located $0\mathrm{.}25$ m from A and is moving downward along the rod with a velocity of $3\frac{m}{s}$ and an acceleration of $2\frac{m}{s^2}.$ Determine the veloc

$$

$$ Solve example $20\mathrm{.}4$ by changing the Reversing the velocity and acceleration of collar $C$ and change ${}_M^{}$ to be $2ra\frac{d}{s^2}$
