You can put this solution on YOUR website! A van travelling at a velocity of 36km/h reaches a velocity of 54km/h after travelling 900m. What is the time taken and the acceleration?
----------
If the acceleration is constant, the average speed of the 900 meter is 45 km/hr
-----
0.9 km/(45 km/hr) = 0.02 hours
= 1.2 minutes
--------------
a = (54 - 36)/0.02 = 900 km/hr/hr
