Answer:

4. B

5. A

6. C

7. A

8. B

9. B

10. D

Explanation:

4. The SI Unit of Speed and Velocity is the ratio of two - meter per second or m/s

5. Because acceleration is velocity divided by time,the SI Unit for acceleration are m/s2 or meter per second squared

6. Velocity requires direction as an object is moving

7. It is the change in position of an object

8. s=d/t (100m/140s)

9. (130km/2hrs.)

10.t=d/v (850km/100km/hr.)
