INTRODUCTION: This is a problem from my Introduction to Physical Science class using "Conceptual Physics" 10th Ed.by Paul G. Hewitt EXACT PROBLEM: "The block in the figure at the right has a mass of 8kg and an initial speed of 7 m/s at Point A. Neglect frictional forces." PROBLEMS FACED: a) What will be its speed when it reaches Point B? b) What will be its speed when it reaches Point C? MY THOUGHTS: Should I be looking for kinetic energy? What am I doing here?
