A boy kicks a ball and it is accelerated uniformly from rest so that after 10 seconds it has achieved a speed of 15m/s. Find the ball's acceleration.

First, clearly set out the information we know: U=0m/s, V=15m/s, T=10s, and identify the value we are wanting to find out: A=? Check that all of these value's units are in meters and seconds only. Recall the equation involving these values: V=U+AT. Rearrange to form A=(V-U)/T. Plug in the numbers we have. Identify the correct unit for acceleration which is m/s2
