It's there, but with the wrong angle.andrewkirk said:
Much closer, but you've left out a contributor to the normal force.goldfish9776 said:

A couple of problems with the term you added.goldfish9776 said:
P cos30 +100x9.81xcos20 -1000x9.81xsin30 = 0.2 ( 1000x9.81cos30 +P sin30 -100x9.81sin30 )haruspex said:
Isn't the angle still wrong?goldfish9776 said:

Ok!goldfish9776 said:
The forces needed to slide up the plane refer to the amount of force required to move an object up an inclined surface.
The forces needed to slide up the plane are influenced by several factors, such as the angle of the incline, the weight of the object, and the coefficient of friction between the object and the surface of the plane.
The forces needed to slide up the plane can be calculated using the formula F = mg sinθ, where F is the force needed, m is the mass of the object, g is the acceleration due to gravity, and θ is the angle of the incline.
Friction plays a crucial role in determining the forces needed to slide up the plane. The coefficient of friction between the object and the surface of the plane determines how much force is needed to overcome the resistance and move the object up the incline.
The forces needed to slide up the plane can be reduced by decreasing the angle of the incline, reducing the weight of the object, and increasing the coefficient of friction between the object and the surface of the plane. Additionally, using lubricants can also help reduce the forces needed to slide up the plane by reducing friction.
