Okay. So I've got three cars that are traveling along a hilly road. One is at the beginning, where its flat, one is at the bottom of the hill, one is at the top. Each is traveling at 21 m/s. I am supposed to find tangential acceleration for each.
I tried:
a = v^2 / r but that is radial acceleration.
I know the formula for tangential acceleration is a = (alpha)(r)
but i am given no times or anything to calculate alpha.
I'm thinking I need a relation of some sort between radial and tangential accelerations.
Anyone have any guidelines?
