How can you find out Acceleration? [Practical]

Grab a trolley and some stopwatches along with a ramp. Measure out the Distance too between the points of interest. Those interests will be the beginning, Runway and the End. The times on the ramp will give you an Average speed on the ramp. [Distance divided by Time] and the time on the runway gives you the speed on the runway. Acceleartion can now be found as the change in velocity is going to be your speed on the ramp/runway. [Initial Velocity was 0]
