Transcript

  • 1. Constant Acceleration 1. The problem A tiger can accelerate from rest to a speed of 28 m/s in 5.9. s. a) What is the average acceleration of the tiger? b) What distance does it travel in this time? 2. At t = 2 s a car has a speed of 30. m/s. After 6.0 s, its speed is 14 m/s. What is its average acceleration during this time interval? 3. Assuming constant acceleration how far does a plane taking off from 30miles/hr travel in 30 seconds to reach a speed of 400 miles/hr? 4. A bus moving at an average deceleration is slowing from 60m/s to 10m/s so that he can pick up a student who is 400 meters away. How long does it take the bus to stop? v vs t graph Solution
  • 2. 5. A car whose initial speed is 30. m/s slows uniformly to 10. m/s in 5.0 seconds. a) Determine the acceleration of the car. b) Determine the distance it travels. 6. A dog runs down his driveway with an initial speed of 5.0 m/s for 8.0 s, then uniformly increases his speed to 10. m/s in 5.0 s. a) 7. What was his acceleration during the 2nd part of the motion? b) How long is the driveway assuming he reached the end after 12.0 seconds? A physics student skis down a hill, accelerating at a constant 2.0 m/s2. If it takes her 15 s to reach the bottom, what is the length of the slope? 8. A mountain goat starts a rock slide and the rocks crash 100. m down the slope. The rocks final velocity avearge out to be 75m/s. How long did it take for the rocks to reach the bottom of the mountain?
