Compute the each parts of following problem:

Problem: A Child of mass 40kg goes down a rough (Coefficient of Kinetic Friction 0.2) slide inclined at 30 degree to the horizontal. The child starts from rest at the top of the slide, which is 4m above the bottom.

Part I: When he reaches the bottom how much work has been done by the friction force?

Part II: How much work has been done by the weight force?

Part III: What is the speed of the child?

Please explain each step and equations used. Thanks.
