More Problems

  1. A rifle fires a bullet at a velocity of 645 m/s. If the bullet travels for .6 seconds, how far will it have traveled?
  2. A conveyor belt that is 60 meters long is moving at a rate of 1.5 meters per second. How much time will it take the belt to complete one cycle? (click the link to see what a conveyor belt looks like)
  3. A maglev train travels a total distance of 35 km from the train station to the airport. It completes this journey in 5 minutes and 25 seconds. What is its average speed during each trip?
  4. A small rat runs 6 meters to escape a diving hawk. He makes it to his burrow in 2.4 seconds and just escapes. What was his velocity?
  5. A Chevrolet Volt accelerates from 15 m/s to 25 m/s in 4 seconds. What was the car's rate of acceleration?
  6. Cam Newton was running at 5 m/s when he had to slow down to avoid a tackler. (This is really painful, fellow 'Bama fans. BEAR with me.) He slowed down at a rate of -3 m/s/s for .7 seconds. What was his final speed?
  7. A small deer was walking at 2 m/s when he was shot by a hunter. He accelerated to 8 m/s in .5 seconds. What was his initial rate of his acceleration?
