A car is tested on a 230 m diameter track.
If the car speeds up at a steady 1.2 m/s^2, how long after starting is the magnitude of its centripetal acceleration equal to the tangential acceleration?
it seems simple, but i just can't seem to get it!...
find: change in time when centripetal acceleration = tangential acceleration.
r = 115 m.
a = 1.2 m/s^2 (which type of a, i don't know)
centripetal accel = v^2/r or w^2/r
tangential accel = (radius)(angular accel)
i tried setting them equal to each other obviously, but no luck. can someone help me out??
