Objective:  SWBAT determine how well they performed on the FRQ section of an AP Physics B Exam.


Warm Up:  Get out your 2009 AP FRQ's.
A 2.0 kg wooden block is on a level board and held against a spring for force constant 100 N/m which has been compresses 0.10 m.  The block is released and propelled horizontally across the board.  The coefficient of friction between the block and the board is 0.20.  Determine the velocity of the block just as it leaves the spring.  Also, determine the distance the block travels after it leaves the spring.
