SPEED/VELOCITY CALCULATIONS:

Use the formulas below to answer questions 1-6. CIRCLE YOUR ANSWERS AND BE SURE TO INCLUDE THE CORRECT UNITS!!

|Equation |Gives you…. |If you know…. |

|S=d/t |Speed (or rate) |Distance and time |

|D= s x t |Distance |Speed (rate) and time |

|T= d/ s |Time |Distance and speed (rate) |

1. How are speed and velocity different?

2. If Luke throws a baseball 50 meters in 3 seconds, what is the average speed (velocity) of the baseball?

3. Goldie Goldfish, a speed swimmer, loves to race around the park’s pond, which is 0.5 miles around. If she can swim 20 laps around the track in 2 hours, what is her average speed?

4. If it takes Emily 3 seconds to run from the batter’s box to first base at an average speed (velocity) of 6.5 meters per second, what is the distance she covers in that time?

5. Isaiah’s calculations of his pet tarantula show that the spider was able to crawl with a speed of 4 cm/s. How long would it take his tarantula to crawl 40 cm?

6. A train travels 225 kilometers in 2.5 hours. What is the train’s average speed?

ACCELERATION CALCULATIONS:

Use the formula below to help you to answer questions 7-10. CIRCLE YOUR ANSWERS AND BE SURE TO INCLUDE THE CORRECT UNITS!!

Acceleration = Ending Velocity – Starting Velocity

Time

7. Toon Train is traveling at the speed of 10 m/s at the top of a hill. Five seconds later it reaches the bottom of the hill and is moving at 30 m/s. What is the rate of acceleration of Toon Train?

8. Monster Mike’s truck decelerates from 72 m/s to 0 m/s in 6 seconds. What is his rate of deceleration?

9. A plane starting from rest is accelerated to its takeoff velocity of 75 m/s during a 5 second period. What is the plane’s rate of acceleration?

10. Randy Roller Coaster rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s, but 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration?
