Question: How much work did friction do on the book? Information: The book from problem 1 is then allowed to slide down a straight ramp which makes a 26.0o angle above the horizontal, and the book reaches its original position at the end of this ramp. If the book is actually going 3.00 m/s, what was the coefficient of friction between thebook and the ramp?

A block of mass 7.50 kg is being pulled along a level surface as shown, by a force directed at 30.0 degrees above horizontal. The pulling force has a magnitude of 68.0 N. Ignore the friction for now. If the total work done by the pulling force is 255 J, then how far has the block traveled? Hints on solving strategy: Remember from Flipping Physics that work is measured in Joules (J). You'll need to use the formula Mr. P gives for calculating the work done by a force over a given displacement.
