A child with a mass of 30.0 kg is moving down a slide at a playground. The angle the slide makes with the ground is 60.0°, and the coefficient of friction between the child and the slide is 0.250. What is the frictional force on the child? You may want to draw a free-body diagram to help you solve the problem.
