The blade on the horizontal$-$axis windmill shown in $($Figure $1)$ is turning with an angular velocity of

${}_0=2ra\frac{d}{s}.$ It is given an angular acceleration of ${}_c=0\mathrm{.}8ra\frac{d}{s^2}.$

Part A

Determine the angular velocity of point $P$ on the tip of the blade when $t=5s.$

Express your answer in radians per second to three significant figures.

${}_P=|$~$,ra\frac{d}{s}$

Part B

Determine the magnitude of acceleration of point $P$ on the tip of the blade when $t=5s.$

Express your answer in feet per square second to three significant figures.
