A car sitting at a red light begins to accelerate at 2 m/s2 when the light turns green. It continues with this acceleration until it reaches a speed of 20 m/s. It then travels at this speed for another few minutes. How far does the car travel in the first 35 s after the light changes to green? Express your answer in meters to one significant figure.

A truck traveling at 50 km/hr approaches a car stopped at a red light. When the truck is 100 m from the car, the light turns green and the car immediately begins to accelerate at 2 m/s2 to a final speed of 100 km/hr. A) • How long does it take for the car to reach its maximum speed? B)During this time, how far does the car travel? C)What is the distance between the truck and the car 20 seconds...

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?

Bob is sitting in his car at a red light. The car is not moving. When the light turns green, he takes his foot off the brake and the net force on the car becomes 3,920.4 N. What is his speed 3.29 s later? The mass of his car is 1,649 kg. Give your answer in m/s.

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 5.6 m/s2 for 3 seconds. It then continues at a constant speed for 7.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 178.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

To save fuel, some truck drivers try to maintain a constant speed when possible. A truck traveling at 30.0 km/hr approaches a car stopped at the red light. When the truck is 195.0 meters from the car the light turns green and the car immediately begins to accelerate at 2.4 m/s2. How close does the truck come to the car assuming the truck does not slow down? How far from the stop light has the car travelled when the truck...

1. To save fuel, some truck drivers try to maintain a constant speed when possible. A truck traveling at 116.0 km/hr approaches a car stopped at the red light. When the truck is 177.4 meters from the car the light turns green and the car immediately begins to accelerate at 3.00 m/s^2 to a final speed of 120.00 km/hr. How close does the truck come to the car assuming the truck does not slow down? 2. How far from the...

A car and a train move together along straight, parallel paths with the same constant cruising speed v0. At t=0 the car driver notices a red light ahead and slows down with constant acceleration −a0. Just as the car comes to a full stop, the light immediately turns green, and the car then accelerates back to its original speed v0 with constant acceleration a0. During the same time interval, the train continues to travel at the constant speed v0. How...

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 3.9 m/s2 for 4.7 seconds. It then continues at a constant speed for 10.2 seconds, before applying the brakes such that the car's speed decreases uniformly coming to rest 254.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...
