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 car gains speed at a constant rate as it moves to the right. It covers the distance between two points 60.0 meters apart in 6.00 seconds. Its speed as it passes the second point is 15.0 m/s. a) What was the velocity of the car at the first point? b) What was the acceleration of the car? c) Assuming the car began from rest and continued with this same acceleration, at what distance before the first point did the car begin?
Karen bikes at 8 mph for 0.3 hours from home to the park. At soon as she arrives, Karen remembers she has a study session with Marie. So, Karen turns around and bikes to Marie's house at 12 mph for 0.1 hours. They study for 0.5 hours. Then, Karen bikes home for 0.4 hours. Note: Marie's house is in between Karen's house and the park. 1. Plot a velocity vs. time graph. 2. Calculate Karen's speed when she bikes from Marie's to her house. 3. Calculate the distance of each segment. 4. Plot a position vs. time graph.
You are driving at night on a straight path at 70MPH. Suddenly, a dog appears in your headlights 35 meters away. You immediatley apply the brakes which causes your car to slow down at a constant rate, coming to rest just before making contact with the dog. 1 mile = 1.61 km 1) How long did it take for your car to make a complete stop? 2) If you were initially driving in the 'positive x' direction, then what was your acceleration during the braking maneuver, in vector form and in m/s2?
