A car is traveling on a straight road and always heads in the same direction. The car starts from rest, undergoes constant acceleration for (tau) seconds to reach a velocity of 45 m/s, and travels afterward at this constant velocity of 45 m/s. The car takes a total time of 35 s to travel a distance of 1220 meters.
Determine
1) The value of (tau)
2) The value of acceleration in the time interval before (tau)
3) The distance travelled before the car reaches 45 m/s
