H.W. Acceleration

Show your work

  1. What is the acceleration of a car that travels south and speeds up from 20m/s to 65 m/s in 30s?

2. If car A goes from 10 to 85 meters in an hour and car B goes from 5 to 25 meters in 20 mins. Who has the greatest acceleration?

3. Emely ran half of 3 meters in 10s , then twice that distance in 8 seconds. At the end of her race, she ran the last 15 meters in 15 seconds.

  • What was Emely’s  velocity during the first , second and last intervals, average velocity,  and acceleration?
  • Draw a graph for Emely’s race.

4. What is the difference between constant acceleration and constant velocity.
