Suppose: Down the plane is the positive direction and up the plane is the negative direction. A block of mass 190 kilogram slides on a frictionless plane inclined at 36o with the horizontal under the influence of a restraining force of 1334 Newton acting parallel to the incline and up the incline. The acceleration of gravity is 9.8m/s^2.
Find the magnitude of the acceleration of the block? Answer in units of m/s^2.
