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.

Explanation:

From work-energy theorem we got that:

(1)

If we see the free body diagram attached we can calculate the work done by the group of students by knowing its definition given by:

Where F is Force and s is distance

These are the forces at the x-axis that are causing the work done by the students

Now, we can calculate the velocity at the top of the ramp using (1)

i would think form in reponse to tensional forces

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.
