Standardized Test Prep Extended Response 16. A student pulls a rope attached to a 10. 0 kg wooden sled and moves the sled across dry snow. The student pulls with a force of 15. 0 N at an angle of 45. 0º. If mk between the sled and the snow is 0. 040, what is the sled’s acceleration?

Standardized Test Prep Extended Response, continued 17. You can keep a 3 kg book from dropping by pushing it horizontally against a wall. Draw force diagrams, and identify all the forces involved. How do they combine to result in a zero net force? Will the force you must supply to hold the book up be different for different types of walls? Design a series of experiments to test your answer. Identify exactly which measurements will be necessary and what equipment you will need. © Houghton Mifflin Harcourt Publishing Company
