A car is driving on I-80 traveling at 75 mph. It passes a police officer on the side of the road who is stationary. The moment that the car passes the police officer, the officer accelerates at a constant rate of 20 ft/s2 until she reaches a speed of 80 mph. At that point, her speed is maintained. a. How far does the police car travel before reaching its full speed (in ft)? b. How far does the car travel while the police car is speeding up (in ft)? c. How far does the police car travel before catching up with the car (in ft)?
A safety measure when driving cars is to leave a separation of "3 s" with respect to the next car. This rule has made it possible to avoid many accidents. a. If a car travels at 60 km / h, what distance (in meters) will it travel in 3 seconds? Assuming there is an accident 20 m from where you are, what acceleration must you have to bring the car to a complete stop before reaching the accident?b. Repeat part a considering a speed of 90 km / hc. Repeat part a considering a speed of 120 km / hd. Repeat part a considering a speed of 150 km / h
2. Two cars are drag racing. The red car accelerates at a rate of 4.7 m/s', and the blue car at a rate of 3.9 m/s’. The blue car starts 1.5 s before the red. Find the time it takes for the red car to be at the same position as the blue car, how the cars have traveled, and how fast each is moving at this time.
At the instant the traffic light turns green, a car starts from rest with a constant acceleration of 3.0 m/s2 . At that instant, a truck travelling with a constant speed of 36 km/h overtakes and passes the car. a. How long does it take the car to overtake the truck? b. How fast will the car be travelling when it overtakes the truck.
