Presentation Transcript

  1. #1 • What unit is time usually measured in? • What unit is distance usually measured in? • What units are used for speed/velocity? • What is the Speed formula? • What is the Velocity formula? Station

  2. #2 • 6. If you knew the velocity & the distance, what formula would you use? • 7. If you knew the velocity & the time, what formula would you use? • 8. What is the difference between Speed and Velocity? • 9. If you are on a merry-go-round, are you accelerating? Please explain your answer. Station

  3. #3 • 10. Halle ran the 500 meter race in 68.33 seconds. What was her speed? • 11. A Lotus will travel 275 meters in 4.71 seconds. What is this car’s average speed?   • 12. Maddycan ride her tricycle at an amazing speed of 3.75 meters per second. How far can she go in 5.0 seconds? Station

  4. #4 • 13. It’s Field Day & you are aiming your water cannon at the principal. You know the cannon will hurl water at 42m/s. You also know you have exactly 8.3 seconds to shoot & run. How close to the principal must you be for a direct hit? • 14. The Japanese bullet train travels 348km/h. Osaka is 789.61 km from the beginning of the train line – Mr. Saki must reach Osaka in 2 hours. Will he make it??? • 15. Bobby covers 300m during the first 15 minutes of his workout. He then rested for 15 minutes before swimming another 250m in 10 minutes. After a 10 minutes rest, he then swam 400m in 20 minutes. • How long did Bobby work out total? • What was the total distance he swam during the workout? • What was Bobby’s average speed during his workout? Station

  5. #5 • 16. An automobile manufacturer claims that its latest model can go from 0 to 115 m/s in 7.5 seconds. What is the car’s acceleration in m/s2? • 17. A fighter jet landing on an aircraft carrier’s flight deck that has a length of 300.0 meters must reduce its speed from about 42.5 m/s to exactly 0.0m/s in 2.0 seconds. What is the jet’s acceleration? • 18. A runner whose initial speed is 29 m/s increases her speed to 43 m/s in order to win a race. If the runner takes 5.0 seconds to complete this increase in her speed, what is her acceleration? Station

  6. #6 • 19. A car is merging onto the expressway with an acceleration of 1.77 m/s2. When it begins down the ramp the car is traveling at a speed of 11.1 m/s. How long will it take for the car to reach a speed of 24.4 m/s? • 20. You are traveling in a car that is moving at a velocity of 20 m/s. Suddenly, a car 10 meters away slams on its’ breaks. At that moment, you also slam on your breaks and slow to 5 m/s. Calculate the acceleration if it took 2 seconds to slow your car down Station
