Vroom-vroom! As soon as a traffic light turns green, a car speeds up from rest to 50.0 mi/h with a constant acceleration of 8.60 mi/hs. In the adjoining bike lane, a cyclist speeds up from rest to 20.0 mi/h with a constant acceleration of 14.5 mi/hs. Each vehicle maintains a constant velocity after reaching its cruising speed.
(a) For how long is the bicycle ahead of the car?
(b) By what maximum distance does the bicycle lead the car?
for b I tried to find distance of car at Veolocity= 20, distance of bike at veolicty=20 by finding t when velocity =20 and then finding distance by using the result of my equation. My answer, 9.6291 is coming up wrong. Help
