1. The problem statement, all variables and given/known data A pair of fuzzy dice is hanging by a string from your rearview mirror. While you are accelerating from a stoplight to 28m/s in 6s, what angle does the string make with the vertical? 2. Relevant equations g, accel. of car is 4 2/3 m/s^2 3. The attempt at a solution http://img505.imageshack.us/img505/8594/physwl0.png [Broken] I just figured the two accelerations were all that was necessary since the string length and mass are not given. So the angle is arctan(4.66/9.8) or 25.43 degrees? I did this in class in under a minute and it seems right but on the other hand it also seems too easy.
