Block A starts from rest and then starts moving up with a constant velocity of -4 m/s. At the same time, Block Bis moving down with velocity vB = 2 m/s and has acceleration defined by aB = -vB. At t = 3 s, what is the velocity (including direction) of Block C? How much (and in what direction) has Block C moved?12527689_10207144597367732_1660329628_n.I'm really clueless about this problem

So am I.

How can an acceleration equal (the negative of) a velocity?

 

Please check the wording.
