**drwls**, Tuesday, October 19, 2010 at 3:14amYou will need to consider both centripetal aceleration (a_r) and tangential acceleration (a_t), which are perpendicular.

3.50 = a_t^2 + a_c^2 = a_c^2 + 0.36

a_c^2 = V^2/R = 3.14 m/s^2

Solve for V when the acceleration of 3.50 m/s^2 is reached. From that, get the time and the number of revolutions
