At 5 seconds, an object's velocity is 9 meters per second. At 8 seconds, the object's velocity is 25 meters per second. Assuming a constant acceleration, what is the acceleration in meters per second per second of the object? (If necessary, round to the nearest hundredth.)

Answers

Acceleration = (change in speed) / (time for the change) .

Change in speed = (25 m/s - 9 m/s) = 16 m/s

Time for the change = (8 sec - 5 sec) = 3 seconds

Acceleration = (change in speed) / (time for the change)

= (16 m/s) / (3 sec)

= (5 and 1/3) m/s² .

(rounded to the nearest hundredth ... 5.33 m/s² . )
