A car sits in an entrance ramp to a freeway, waiting for abreak in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 21.0 m/s when it reaches the end of the ramp, which has length 124 m .

1-

What is the acceleration of the car?

2-How much time does it take the car to travel the length of the ramp?

3-The traffic on the freeway is moving at a constant speed of 21.0 m/s . What distance does the traffic travel while the car is moving the length of the ramp?
