A block moves up a 30° incline under the action of certain forces, three of which are shown at the right. F1 is horizontal and of magnitude 40 N. F2 is normal to the plane and of magnitude 20 N. F3 is parallel to the plane and magnitude 30 N. (a) Determin...

A Physics professor is pushed up on a ramp inclined at an angle of 35.0° above the horizontal as he sits in his desk chair that slides on frictionless rollers. The combined mass of the professor and the chair is 86.0 kg. He pushed at a distance 2.95 m alo...
