Exercise Respond to the following based on your reading.

1. Differentiate between speed and velocity.

2. Using examples to describe each term, differentiate among average, instantaneous, and uniform velocity.

Solve each problem.

3. A driver of a car hits its brakes and begins to decelerate. If the velocity changes from 60 m/s to 20 m/s in 6 s, what is the deceleration of the car?

4. A researcher observes a vehicle with an initial velocity of 14 m/s. The vehicle accelerates uniformly with an acceleration of 3 m/s2. After 6 seconds, what is the velocity of the vehicle?

5. It takes you 5 hours to complete a 375-kilometer trip. What was your average speed on this trip?

6. Henry takes a boat ride for 15 minutes to reach his destination. If the boat was traveling at 6 meters/second, how far did the boat travel?

7. A storm is moving east towards your house at an average speed of 35 km/hr. If the storm is currently 80 kilometers from your house, in how much time do you expect it to arrive?

8. If the velocity of an object changes from 15 m/s to 50 m/s during a time interval of 4 s, what is the acceleration of the object?

9. If the acceleration in question 8 is constant, what's the average velocity of the object described?

10. A van is traveling at 11.5 m/s. To avoid hitting a deer, the brakes are applied, and the van stops within 3.5 seconds. What is the acceleration?
