1. A bird flying between trees changes its position from 121 m [W] of a flagpole to 64 m [E]. What is the displacement of the bird?

2. During a straightaway, a race car travels a distance of 280 m in 4.3 s. What is the average speed of the race car on the straightaway?

3. A bird is hunting for food and flies 420 m [E] from its nest in 14.4 s. What is the average velocity of the bird during its flight?

4. A car travels from 32 km [W] of a railroad to 27 km [E] of the railroad in 1.8 h. What is the velocity of the car in metres per second?

5. A runner leaves from his home, and in 1.6 s his speed is 2.8 m/s. Determine the acceleration of the runner.

6. A race horse starts running once the gates fall and accelerates at a rate of 7.10 m/s for 2.20 s. What is the Final speed of the horse?

7. An arrow is shot from a crossbow. How long will it take the arrow to accelerate from rest to a speed of 152 m/s if the crossbow can accelerate the arrow at a rate of 1.35 x 104 m/s?

8. A skier is going 8.2 m/s when she falls and starts sliding down the ski run. After 3.0 s, her velocity is 3.1 m/s. How long after she fell did she finally come to a stop? (Assume that her acceleration was constant.)

9. You throw a rock off a cliff, giving it a velocity of 8.3 m/s, straight down. At the instant you released the rock, your hiking buddy started a stopwatch. You heard the splash when the rock hit the river below, exactly 6.9 s after you threw the rock. How high is the cliff above the river?

10. A soccer player kicks a ball from the ground with an initial velocity of 24 m/s at an angle of 62 to the horizontal. Determine the maximum height and the total time of flight for the ball.

11. A car travels east along a straight road at a constant velocity of 18 m/s. After 5.0 s, it accelerates uniformly for 4.0 s. When it reaches a velocity of 24 m/s, the car proceeds with uniform motion for 6.0 s. Determine the car's total displacement during the trip.

12. A truck is travelling at a constant velocity of 22 m/s north, The driver sees a traffic light turn from red to green soon enough, so he does not have to alter his speed. Meanwhile, a woman in a sports car is stopped at the red light. At the moment the light turns green and the truck passes her, she begins to accelerate at 4.8 m/s. How far have both vehicles travelled when the sports car catches up with the truck? How long did it take for the sports car to catch up with the truck?
