5. ( ) A professor on a wheelchair is pushed up a rample of angle alpha and height 'h' by her students with a horizontal force of F. (A) If the coeffiicient of kinetic friction between the chair and ramp is "uk" (constant), find the velocity of the professor at the end of the ramp. (B) Now assume uk is not constant but uk=Ax. Find again the velocity at the end of the ramp.
