Question

Hoping for complete solutions since I’m having a hard time with this. The question is asking for both an instantenous position x(t) and velocity v(t) equations. Pls skip if unsure or not willing to answer the subquestions A-E (these are all connected for one item). Thanks in advanced!

A. Draw the free body diagram of block A and Block B.
Draw the x and y axis. (Hint: The string is taut all the time)

B.  What is the acceleration of block ? in the first 3.00 [s] if both blocks start from rest?

C. From your answer in (b), write the acceleration of block B

D. Write Newton’s 2nd law for block A along the horizontal direction and solve for the magnitude of the force exerted by the rope on block A

E.  Write Newton’s 2nd law for block ? along the horizontal direction and solve for its unknown
