Q12. Peg Pis driven by the fork link OA along the curved path described by r = (C· 0) m, where C = 1.O. At the instant 0 = 1.2 rad, the angular velocity and angular acceleration of the link are 0 = 2.1 rad/s and 0 = 0.9 rad/s?. Determine the magnitude of the peg's acceleration (in m/s2) at this instant. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.

Please do this carefully.

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)?   https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.
