A piston is driven by a crankshaft as shown. The crank arm $($member $AB)$ has a length of $r_1=0\mathrm{.}55$ in and the connecting rod $($member $BC)$ has a length of $r_2=3\mathrm{.}05$ in $.$ The crankshaft rotates in the counterclockwise or positive direction.$($Figure $1)$

Part C $-$ Velocity of $C$

Find the magnitude of the velocity of $C,v_C,$ when the piston has moved to the new position $=27\mathrm{.}0$ and $=9\mathrm{.}25.$ The crankshaft $($member $AB)$ is still rotating at $240$ rpm $.$ Express your amper to three significant figures and include the appropriate units.
