i've drawn a free body diagram and got my equations to be
x=-490sin30 + f=50a
y=-490cos30 + n = 50a
and now I am stuck

rl.bhat said:Correct.
When the acceleration is zero on an inclined plane with friction?
Along with the frictional force you have to overcome the component of weight in that direction to pull the crate up.zhangster11 said:the direction of friction would be downward and to move the crate, you would need a force equal to the force of friction?
Friction is a force that occurs when two surfaces come into contact with each other and resist motion. It is caused by microscopic bumps and ridges on the surfaces that interlock and create resistance to movement.
Friction is calculated by multiplying the coefficient of friction (a constant that represents the roughness of the surfaces) by the normal force (the force perpendicular to the surface). The resulting value is the force of friction.
Some examples of friction in everyday life include walking (between your shoes and the ground), writing (between the pen/pencil and paper), and driving (between the tires and the road).
Friction can either slow down or stop motion, as it acts in the opposite direction of the applied force. It also converts kinetic energy into heat, which can further slow down an object's motion.
Friction can be reduced by using lubricants (such as oil or grease) between surfaces, using smoother surfaces, or reducing the force pushing the surfaces together (such as using wheels instead of sliding objects). However, completely eliminating friction is impossible.
