Use the equation F = ma,
but be sure F is the NET force up the incline. The net force will be the resultant of applied force, friction (if present) and gravity terms.
A similar question was submitted yesterday. Was it by you?
A more detailed answer was provided then.
How would I go about calculating the acceleration of a mass being pulled up an inclined plane at an angle.
Given - mass, and presumably angles
So the object is being pulled up an angle at another angle.
