A car with a mass of 1Mg is at rest at a stoplight. When the light turns green, the car's engine applies a force resulting in a net force of 2kN acting on the car to the east for 10s.

a) Calculate the acceleration that the car experiences.

b) Calculate the final velocity of the car at the end of the 10 seconds.

c) Calculate the initial momentum of the car.

d) Calculate the final momentum of the car.

e) Calculate the car’s change in momentum.

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.7 m/s2 for 3.1 seconds. It then continues at a constant speed for 8.4 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 202 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

As soon as a traffic light turns green, a car speeds up from rest to 52.0 mi/h with constant acceleration 8.00 mi/h/s. In the adjoining bike lane, a cyclist speeds up from rest to 21.0 mi/h with constant acceleration 14.00 mi/h/s. 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?
