Wet 'n Wild has a waterslide called Daredevil Drop. At the steepest part of the slide, the angle is about . A girl goes down the slide. Her mass is 40 kg and the frictional force of the slide on her at its steepest angle at is 20 N.
- What is the normal (compression) component of the force by the slide on the girl?
- What is the girl's acceleration?
- What is the fundamental cause of the normal force by the slide on the girl?
