A car sits in an entranceramp to a freeway, waiting for a break in the traffic. The driveraccelerates with constant acceleration along the ramp and onto thefreeway. The car starts from rest, moves in a straight line, andhas a speed of 25 m/s (56 mi/h) when it reaches the end of the120 m long ramp.

(a) What is the acceleration of the car?

(b) How much time does it take the car to travel the length of theramp?

(c) The traffic on the freeway is moving at a constant speed of25 m/s. What distance does the traffictravel while the car is moving the length of the ramp?
