Dr. Bradshaw builds a slide. By lifting one side, he finds that when the slide makes an angle of 32 degrees with the horizontal, Jackson begins to slide.
(a) what is the coefficient of static friction?
(b) While Jackson is sliding down the incline, Maria tries to pull him back up the incline using the rope that is attached to him from the top of the slide. As she pulls, the tension in the rope is 435 N up the incline. The coefficient of kinetic friction is 0.1. What is Jackson's acceleration?
