Pre-reading question: (multiple choice)
If a raw egg is thrown as hard as possible at a wall, it will break. What will happen if it is thrown just as hard at a loose bed sheet?
And now an experiment:
A 5-kg block is released from rest and slides 10 meters down a frictionless ramp inclined at 30 degrees.
•Sketch an Energy-position graph for the block. Label the PE, KE, and TME (total mechanical energy).
•What is the speed of the block when it reaches the bottom of the ramp?
