I kno it would help to have a picture but please try to imagine it..its a connected mass problem on an incline plane

Starting from rest, it takes 4 seconds for block B..which is m2..(the one hanging) to reach the ground 2 meters belown..what is the coefficient of friction needed between block A..m1 (the one on the incline) and a 30 degree incline plane so that this will occur...block B= 6 kg...block A= 8 kg

PLEASE HELP ME IF U KNO..THANX

im thinkin i would have to find the acceleration first so would it be 0.125m/s/s because a=v/t...and v=d/t

v=d/t...2meters/4seconds=0.5m/s and then since a=v/t...0.5m/s divided by 4 seconds is 0.125 m/s/s which is acceleration..well that's what i think..am i off or is this rite? then how do i find the coefficient?
