At an instant the block(M = 33kg) is moving down the slope.
Angle between slope and floor = 33deg
Force Pulling up the slope 49N at 38deg to the slope
What is the acceleration of the block up the slope if the kinetic coefficient of friction is 0.5?
My first thought was that all movement was up and down the plane so I summed the forces perpendicular to the normal, divide by the mass (F/m = a) but couldn't get the right answer.
