1. The problem statement, all variables and given/known data A car starts from rest on a curve with radius 150m, with an acceleration of 1.8 m/s2. How many revolutions will the car make before the magnitude of its acceleration is 2.40 m/s2? 2. Relevant equations at2 + ar2 = total acceleration2 theta = omega (t) + .5 (acceleration) (t)2 3. The attempt at a solution I solved for velocity by plugging in v2/ R into the acceleration triangle equation. Then I solved for "t" by dividing my velocity by the acceleration and got 15 m/s for velocity and 8.3 seconds for time. I plugged that into the position equation and got 62.5 radians, divided by 2pi and got 9.95 revolutions. That was wrong - tips please?
