AP Extra Problems for Unit 3 errors

Unfortunately I uploaded the wrong version of the extra problems. With the help of Sydney Orthmann I have uncovered a couple of errors and there may be more.

The errors so far are the tension in problem 7 should be 4 N ( you should have found the acceleration = 2m/s2) ; the answers c and d showing for problem 13 belong to problem 14 and the a for problem 14 is -6.6 m/s2. I will try to locate the correct version, but in the mean time stick with this one and I'll try to get through all the odd problems to check the answers by tomorrow.
