An object of mass M = 924 g is pushed at a constant speed up a frictionless inclined surface which forms an angle è = 50 degrees with the horizontal as shown in the figure below. What is the magnitude of the force that is exerted by the inclined surface on the object?

There is an F shown, at an angle in the figure.

  • physics -

    That angle is important.

  • physics -

    The direction of the applied force is important, and so it the angle of the incline. Apply vertical and horizontal forces balance equations to solve.

    Thank you
