- 2.A person riding a bike travels 214 meters in 58 seconds. Calculate the person's velocity.
- 3.A train maintains a constant velocity of 16.0 meters per second. Calculate the distance the train has traveled after 26.0 seconds.
- 4.A speedboat maintains a constant velocity of 12.00 meters per second. Calculate the time it will take for the boat to travel 400.00 meters.
- 5.A car maintains an constant velocity of 18.0 meters per second. Calculate the distance the car has traveled after 1.50 minutes. (Be careful to watch the units!)
- 6.A taxi maintains a constant velocity of 19.0 meters per second. Calculate the time it takes to travel 2.0 kilometers. (Be careful to watch the units!)
- 7.An airplane maintaining a constant velocity of 30.0 meters per second encounters a tailwind (from behind) of 15 meters per second. Assuming the pilot takes no action to speed up or slow down the plane, calculate the plane's new resultant velocity.
- 8.A golf ball has a constant velocity of 21 meters per second traveling North. It encounters a strong 12 m/s wind
__from__the west. Calculate the ball's new resultant velocity. (You will need graph paper or the Pythagorean Theorem!)
