Checkpoint. Please continue working Tutorial Section 4.5 - The definition of work, and conservation of energy (part 2) Glider A is pulled by a string across a level, frictionless table. The string exerts a constant horizontal force. 1. Complete Section IIA and IIB of the Work and the Work-Energy Theorem in the tutorial book Checkpoint. Please continue working Tutorial Section 4.6 - Revisiting the experiment Consider the first experiment from section 1. 1. How much work does each force do on the glider during your first experiment? Consider forces in both the horizontal and vertical directions. Why? 2. What is the net work done on the glider in your first experiment? 50
