Motion Practice Part I: Speed & Velocity

1) A high school athlete runs 1.00 x 102meters in 12.20 seconds. What is her speed in m/s and in km/h?

2) Casey walks 13 km in 2.0 hours. What is his average speedin km/h and in m/s?

3) Lauren is taking a train to visit her BFF. As the train pulls out of the station, she notices a marker that says 0.0 m. She starts reading a book, and looks up in time to see the train pass the 1620.0 m marker.

a. If the train was traveling at a constant velocity of 36 m/s, how long had Lauren been reading?

b. What is the velocity of the train in km/h?

4) At 1:00 PM a car, traveling west at a constant velocity of 94 km/h, is 17 km to the west of Baker. Where will this car be at 3:30, assuming it maintains its velocity?

5)Suppose that the car started 17 km EAST of Baker at the same time.

a. Where would it be at 3:30?

b. At what time would it pass Baker?

6) Light from the sun reaches Earth in 8.32 minutes. The velocity of light is 3.00 x 108 m/s. How far is Earth from the sun? Express this answer in meters, kilometers, and miles.

a)Meters:

b)Kilometers:

7) You and your friend each drive 50 km. You travel at 90 km/h and your friend travels at 95 km/h. Assuming you both left at the exact same time, how long will your friend have to wait for you after he reaches the destination?

8) A motorist drives north for 35 minutes at 85.0 km/h, and then stops for 15 minutes. He then continues north, traveling 130 km in 2.00 hours.

a)What was his total displacement?

b)What was his average velocity? You must include his periods of rest!

9)It took the Apollo spacecraft about 5 days to reach the moon from Earth. The distance from Earth to the Moon is 3.8 x 108 meters. What was the speed of the Apollo spacecraft, in m/s?
