Suppose that vCvC $=7\mathrm{.}5$ ft$/$sft$/$s$.($Figure $1)$

Part A

Determine the angular velocity of link ABAB at the instant $=30.$

Express your answer in radians per second to three significant figures. Assume the positive direction is counterclockwise.

Part B

Determine the angular velocity of link $\backslash ($ B C $\backslash )$ at the instant $\backslash (\backslash$theta$=30^\{\backslash$circ$\}\backslash ).$

Express your answer in radians per second to three significant fiqures. Assume the positive direction is counterclockwise.
