At a junction, when the traffic light turns green, a car (A) at
rest begins to roll with an acceleration of 2.2 m / s2. Always when
the traffic light turns green (at t = 0), a second car (B)
traveling at a speed of 9.5 m / s exceeds the first car.
a. How far from the junction will the car catch up with car
B?
b. What is the modulus of its speed?

Review. As soon as a traffic light turns green, a car speeds up from rest to 22.35 m/s with constant acceleration 4.02 m/s2. In the adjoining bicycle lane, a cyclist speeds up from rest to 8.94 m/s with constant acceleration 5.81m/s2. Each vehicle maintains constant velocity after reaching its cruising speed. (a) For what time interval is the bicycle ahead of the car? (b) By what maximum distance does the bicycle lead the car? Give it with detailed explanation please.
