How fast (in rpm) must a centrifuge rotate if a particle 6.7 cm from the axis of rotation is to experience an acceleration of 200000 g’s? Express your answer using two significant figures

1. A stopwatch starts while race car travels at 13 m/s from the pit area and accelerates at a uniform rate to a speed of 37 m/s in 5 s moving on a circular track of radius 548 m. Assuming constant tangential acceleration, find (a) the tangential acceleration, and (b) the radial acceleration,at the instant when the speed is v=7 Once you have both of those…. find the magnitude of a at any moment a= 2.
