A speeding car traveling at a constant velocity of 24 m/s passes a police care initially at rest beside the roadway. If the police car with constant acceleration of 6.05 m ⁄ s^2 immediately pursues the speeding car, how far down the road does it draw even with the speeding car?
A police officer with a radar gun clocks a speeding car as traveling 74 km/h along a country lane. Assume that the police officer starts accelerating 5 seconds after the speeding car passes by and in order to catch up with the car. Assume the car travels at the same speed for 6 seconds, then slows down to 77 % of the original speed. What minimumacceleration will allow the officer to catch up with the car in 25 seconds? Express...
A speeding car is traveling at a constant 25 m/s when it passes a stationary police car. If the police car delays for 1.00 s before starting, what must be the magnitude of the constant acceleration of the police car to catch the speeding car after the police car travels a distance of 371 m?
5. A car traveling at 15 m/s passes a police car. At that instant, the police car accelerates at a constant rate of 3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. Choose a coordinate system for this problem and identify the initial states starting when the car passes the police. a. b sr ei eion
Please show work 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...

(10%) Problem 9: Slick Willy is in traffic court (again) contesting a $50.00 ticket for speeding. The speed limit was vo 50 mph and the police officer clocked Slick going vsw 68 mph. However, he was caught by a police officer driving towards him, so he is arguing that although the police officer measured him to be speeding, in reality he was not. Slick Willy is assuming that the Doppler shift in electromagnetic radiation is described in the same way...
Answers these two questions step by step 13. From a hot-air balloon at rest, 150 m above ground, a rock is thrown downwards with a speed of 15 m/s at the same time an identical rock is dropped (initial velocity- 0) from the same height. How much time separates their landings? the cannon (B), the car is traveling at 10 m/s speeding up at a constant rate of 0.5 m/s?. The instant it passes the cannon (B), the cannon fires...
A car traveling at 45 m/s passes a stationary motorcycle cop. The motorcycle cop starts accelerating at 3.5 m/s2 instant the car passes him. What is the Displacement of both the car and motorcycle?
A driver travels northbound on a highway at a speed of 23.0 m/s. A police car, traveling northbound at a speed of 44.0 m/s, approaches with its siren producing sound at a frequency of 2600 Hz. What frequency does the driver observe after police car passes him? (Assume room temperature of 20°C when determining the speed of sound.) a. 3183 b. 2459 Cc.
