[Einstein Uae]

answer for question # 7

To accelerate the mass up the incline will require the application of an external force that can so 2 things: overcome the gravitational component acting parallel to the incline [Fparallel=Fg*sin(Q)] and generate the required acceleration [F=m*a]. Therefore, the required force will be: Fa = Fparallel+F = m*g*sin(Q)+m*a.

So use this equation

Fa = m*g*sin(theta) + m*a

m is the mas of the box
g is the acceleration of gravity
a is the acceleration given of the box
