Two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. Block A has mass 15.0 [kg], and block B has mass m. A constant horizontal force F=80.0 [N] is applied to block A. In the first 3.00 [s] after the force is applied, block A moves 18.0 [m] to the right 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
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
mass m. (Hint: Frope on A = Frope on B)
