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 . )

Step-by-step explanation:
use the acroname sohcahtoa
<em><u>sin </u></em><em><u>6</u></em><em><u>0</u></em><em><u>=</u></em><em><u>8</u></em><em><u>√</u></em><em><u>3</u></em><em><u>/</u></em><em><u>h</u></em>
sin60=0.8660 while 8√3=13.8564
divide both side by 0.8660
0.8660/0.8660=13.8564/0.8660
h=16.0
