  1. The fastest fish, the sailfish can swim 120 km/h. Suppose you have a friend who lives on an island 16 km from shore. How long would it take to send a message with the sailfish?

  2. Joe wants to set the world’s stair climbing record for climbing up the 443 m tall Sears Tower in Chicago. If his upward average speed is 0.6 m/s,how long will it take him?

  3. A fast moving boat undergoes an average acceleration of 1.8 m/s2. It can accelerate up to a top speed in 8.56 s. If it starts from rest, what is the top speed of the boat?

  4. A train approaches a station with velocity 24.7 m/s, when it begins a constant acceleration of -0.85 m/s2. The acceleration continues for 28 s. What is the trains final velocity?

  5. If the train continues to decelerate and comes to a complete stop, how long would it take to stop from its initial velocity? (the initial velocity was 24.7 m/s, and the acceleration was -0.85 m/s2)

  6. A student on in-line skates travels at a speed of 4.5 m/s along the top of a hill. She then skates downhill with an average acceleration of 0.85 m/s2. If her final speed is 10.8 m/s, how long does it take her to skate down the hill?

  7. Suppose a polar bear running with an initial speed of 4.0 m/s accelerates uniformly for 18 s. If the bear travels 135 m during the 18 s, What is the acceleration?

  8. A motorcycle starts from rest and accelerates uniformly over a certain distance. If the acceleration is 0.2 m/s2 and final velocity is 0.8 m/s, how long does it take to go the distance? How far does it go?

  9. A car with a velocity of 22 m/s accelerates uniformly at the rate of 1.6 m/s2 for 6.8 s. What is its final velocity?

  10. A barge moving with a speed of 1.00 m/s increases speed uniformly, so that in 30.0 s it has traveled 60.2 m. What is the magnitude of the barge’s acceleration?

  11. A plane travels 500 m while being accelerated uniformly from rest at a rate of 5 m/s2. What final velocity does it reach? How long does it take to reach this velocity?

  12. A baseball pitcher throws a fastball with a speed of 44 m/s. The acceleration occurs as the pitcher moves the ball through an almost straight-line distance of 2.5 m. What is the acceleration the ball undergoes? ………

  13. A radio-controlled toy car increases speed over a distance of 15.2 m. If the car starts at rest and has a final speed of 0.76 m/s,what is the magnitude of its acceleration?

  14. Suppose a squirrel throws a walnut from the top of a 111 m tall giant redwood. If the walnut takes 3.8 s to fall, what is the initial and final velocity?

  15. A ball is thrown upward with a velocity of 5 m/s . How long does it take the ball to reach its maximum height? How far up does it reach? How long does it take to come back down? What is the final velocity of the ball when it comes back?

  16. Suppose instead the ball was thrown down 125 m with a velocity of 5 m/s from the same building, what would the ball’s final velocity be? How long would it take to hit the ground?

  17. Fleas have been recorded jumping as high as 21 cm. If the jump is entirely vertical, what does the initial velocity have to be? How long does it take the flea to reach 21 cm?

  18. Car A passes Car B with a constant velocity of 25 m/s. If Car B begins to accelerate form rest at a rate of 2.25 m/s2 the moment that Car A passes it, how long does it take Car B to catch up to Car A? How far have they driven when this happens?
