| On May 29, 1988, Rick Mears won the Indy 500 in 3.45 h. What was his average speed during the 500-mile race? Express your answer in m/s. | 65 m/s |
| Hans stands at the rim of the Grand Canyon and yodels down to the bottom. He hears his yodel echo back from the canyon floor 2.50 s later. Assume that the speed of sound in air is 340 m/s. How deep is the canyon at this location? | 425 m |
| The horse racing record for a 1.50-mile track is shared by two horses: Fiddle Isle, who ran the race in 143 s on March 21, 1970, and John Henry, who ran the same distance in an equal time on March 16, 1980. What were the horses' average speed in mi/h and m/s? | 37.8 mi/h; 16.9 m/s |
| A horse canters away from its trainer in a straight line, moving 130 m away in 14.0 s. It then turns abruptly and gallops halfway back in 4.8 s. Calculate its average speed and its average velocity. | 10.4 m/s; 3.5 m/s |
| What is the acceleration of a rocket ship in outer space that takes 5.0 s to increase its speed from 1240 m/s to 1300 m/s? | 12 m/s^2 |
| A car is going 8.0 m/s on an access road into a highway, and then accelerates at 1.8 m/s^2 for 7.2 s. How fast is it going then? | 21 m/s |
| If a car accelerates at 3.2 m/s^2, how long will it take to speed up from 15 m/s to 22 m/s? | 2.2 s |
| While driving his sports car at 20.0 m/s down a four-lane highway, Eddie comes up behind a slow-moving dump truck and decides to pass it in the left-hand lane. If Eddie can accelerate at 5.00 m/s^2, how long will it take for him to reach a speed of 30.0 m/s? | 2.00 s |
| Monica is walking to the hairdresser's at 1.3 m/s when she glances at her watch and realizes that she is going to be late for her appointment. Monica gradually quickens her pace at a rate of 0.090 m/s^2. What is Monica's speed after 10.0 s? | 2.2 m/s |
| A car accelerates along a straight road from rest to 75 km/h in 5.0 s. What is the magnitude of its average acceleration? | 4.2 m/s^2 |
