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??

Best ResponseYou've already chosen the best response.0I 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.
