1) A student does 125.0 J of work lifting a 12.0 kg book. How high was the book lifted? 1.06m hgh 2) The book from problem 1 is then allowed to slide down a straight ramp which makes a 26.0° angle above the horizontal, and the book reaches its original position at the end of this ramp. How fast would it be going if there was no friction? 6.80 mls 3) If the book is actually going 3.00 m/s, what was the coefficient of friction between the book and the ramp?
