A block accelerates at 3.7 m/s2 down a plane inclined at an angle 27.0. Find μk between the block and the in- clined plane. The acceleration of gravity is 9.81 m/s2 . so i tried this : m * a = m*g*sinA- uk*m*g*cosA a= g*sinA - uk *g*cosA 3.7=9.81 * sin 27 -uk * 9.81 * cos 27 3.7 = 4.45 - 8.74uk 3.7 - 4.45 = -8.74uk .09 = uk ???? yes no maybe??

I got the same numbers.. But I recomend that you don't fill in numbers to the equations until at the end. Teacher doesn't care about arithmatic errors as much as not being able to follow the variables.. Trust me on that.
your sol is right
no its not....
