For this problem,

Is the length vector into or out of the page and how do you tell?

EDIT: Why must we use conservation of energy for this problem? I tried solving it like this:

##IdB\sin90 = ma ##

##IdB = ma ##

##v_f = (2aL)^{1/2} ##

##v_f = (\frac {2dIBL} {m})^{1/2} ##

Which is incorrect according to solutions:

Many thanks!
