Pratice exam 1 over Chapters 1-5. Note that there could also be problems based on lab activities, so study those as well. UPDATE: Problem 6 was revised since the original set up had unintended consequences. Brief solutions: 1. a) t=27.6s; b) t=235s; c) t=470sec (approx.) with d(A)=3760m, d(B)=3055m, d(C)=2256m. 2. a) draw a parabola, straight line with negative slope, constant less than zero 3. b) 16m/s at an angle about 58 degrees from the vertical. 4. a) 6.1m at an angle of -23 degrees, b) x component is always -1.2 m/s^2, while y component is 2.4 and 4.8 m/s^2, for t=2s and t=4s respectively. 5. a) mass = 1.6kg, b) 16N. 6. a) a=23m/s^2 (big!), b) the tensions are 200N, 150N, and 50N, c) the acceleration stops and boxes slow down and stop from friction. Hope I didn't make any mistakes! Let me know if I need to discuss any problems in class!

Exam 1 Worked Solutions. The average was 67.5. I will add 2.5 points to the score to curve the average to 70 when I compute final grades.

I think practice exam 2 (chapters 6-10) may be a little easier than the real one, but it should give you an idea of what to expect. We will go thought it in class Wednesday. Solutions.

Homework will all be done using the Mastering Physics system.
To register, follow the directions in the syllabus. The normal deadline will be Tuesday evenings at 11pm.
Note that there was a typo in the course number to use. Use MSB14Phys1210 instead of MSB12Phys1210. Sorry for any confusion!
