Acceleration Problems

1. A car slows down from 26m/s to 18m/s. Its acceleration is -2.0m/s^2. How long did it take the car to slow down?

2. A car moves at a constant speed of 75 mph for a period of 45 min.
Calculate its acceleration.

3. A runner drops his speed from 20m/s to 10m/s in a time of 2.0s. What was your average acceleration?

4. If a fish experiences an acceleration of 9.8m/s^2 in a time period of 1.84s, what was the change in velocity in the fish?

5. If a car slows down from 26m/s to 18m/s in a period of 4.0 s, what was its average acceleration?

6. If a rock falls with a speed of 112m/s due to gravity of 9.8 m/s^2, for how much time fell?

7. A runner increases his speed from rest to 20m/s in a period of 2.0s. Which was its average acceleration?

8. The speed of a car increases from 2.0m/s to 16m/s in a time of 3.5 s. Which was its average acceleration?

9. What is the average speed in the time interval between 3 and 4 seconds in the chart below?

10. From the graph above, what is the average velocity in the time interval between 1 second to 3 seconds?

Graph will be attached below for #9-10!!!
