You see a car pass, but only see the car as it passes between tall buildings. The width of the alleyway between two buildings is 7 m. You see the car for 0.2 s. You also heard the engine rev when the car started from a red light, so you know the car started from rest 5 s before you first saw it. Find acceleration.

At a stop light, a truck travelling at 15 m/s passes a car as it starts from rest. The truck travels as constant velocity and the car accelerates at 3 m/s^2. How much time does the car take to catch up to the truck? a. 25 s b. 20 s c. 15 s d. 10 s e. 5 s Starting at time t = 0, an object moves along a straight line. Its coordinate in meters is given...

When the drivers pass each other, the driver of the red car is
to toss a package of contraband to the other driver. To catch the
toss on video, one of the cameras must be set up near the point
where the toss will be made. When “action” is yelled out on the
set, the initial separation between the drivers will be 200 m, the
red car will accelerate from rest at a constant 6.12

3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...

A person driving her car at a speed v= 38.0 km/h approaches an intersection just as the traffic light turns yellow. She knows that the traffic light lasts only 1.5 sec, before turning to red, and she is a distance d= 30.0 m away from the near side of the intersection (see figure). The width of the intersection is w = 13.9 m. Her car's maximum deceleration is -5.50 m/s, and its maximum acceleration is 0.950 m/s2. - W -...

You are observing the poles along the side of the road. You have already stopped and measured the distance between adjacent poles as 41.1 m. You are now driving again and have activated your smartphone stopwatch. You start the stopwatch at t = 0 as you pass pole #1. At pole #2, the stopwatch reads 10.3 s. At pole #3, the stopwatch reads 26.8 s. Your friend tells you that he was pressing the brake and slowing down the car...
