How many revolutions will the car have gone, Ask an Expert

Academics

Q. A car starts from rest on a curve with a radius of 110 and accelerates at 0.500 . How many revolutions will the car have gone through when the magnitude of its total acceleration is 3.50 ?

Q. A subway train accelerates from rest at one station at a rate of 1.30 m/s^2 for half the distance to the next station, then decelerates at this same rate for the second half of the distance. If the stations are 4200m apart find the time of travel (in seconds) between the two stations.
