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 compo...

A tennis ball of mass 57. g bounces off a wall. Right before hitting the wall, the ball is moving to the right and up with vx=+40. m/s and vy=+10. m/s. Right after bouncing off the wall, the ball is moving to the left and up with vx=-35. m/s and vy=+10. m/s. If the ball is in ...

An object of mass M = 1,338 g is pushed at a constant speed up a frictionless inclined surface which forms an angle θ = 50 degrees with the horizontal. Incline is increasing. What is the magnitude of the force that is exerted by the inclined surface on the object?

**Physics**

All forces in this problem act on an object along the same axis. Two forces have values -5N +10N respectively. What should be done to bring the system into mechanical equilibrium???

**Physics**

That is weird I had posted a question before!! lol anyways the question was; All forces in this problem act on an object along the same axis. Two forces have values -5N +10N respectively. What should be done to bring the system into mechanical equilibrium??? add a third force ...

**Physics**

All forces in this problem act on an object along the same axis. Two forces have values F = - 5 N and f = +10 N. What do we do to bring the objects in mechanical equilibrium?

ok, so what do you mean by component of weight? anyways, this is what i thought should be the answer F= mgsin(θ) is that correct?
