hello ok i realized what you meant. =)
An object of mass M = 921 g is pushed at a constant speed up a frictionless inclined surface which forms an angle θ = 50o with the horizontal. The normal force acts perpendicular to the slope. The slope is the x-component and y component is the normal force. (i.e. slope is the x-axis)
What is the magnitude of the force that is exerted by the inclined surface on the object?
