Aphysics professor is pushed up a ramp inclined upward at an angle 32.0° above the horizontal as she sits in her desk chair, which moves on frictionless rollers. the combined mass of the professor and chair is 86.0 kg . she is pushed a distance 2.30 m along the incline by a group of students who together exert a constant horizontal force (not parallel to the incline) of 599 n . dr. moreno's speed at the bottom of the ramp is 1.70 m/s. find velocity at the top of the ramp.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
