telescope goes from being stationary to traveling at a speed of 1700 m/s in 25

seconds. What is the acceleration of the satellite?

- A dragster in a race accelerated from stop to 60 m/s by the time it reached the

finish line. The dragster moved in a straight line and traveled from the starting line to

the finish line in 8.0 sec. What was the acceleration of the dragster?
