Answer:
Explanation:
we know that 1 km =1000 m and 1 hour=3600 sec
therefore
15 km/hr=15*1000 m/3600 sec=4.167 m/s
Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
Change in speed = (25 m/s) - (5 m/s) = 20 m/s
Time for the change = 20 sec
Acceleration = (20 m/s) / (20 sec)
<em>Acceleration = 1 m/s²</em>
No that is incorrect. If the results do not support the hypothesis than the hypothesis could have been incorrect. Or there is a possibility that the experiment was not done properly. A hypothesis is an educated guess for the results of the experiment.
