The formula of acceleration is:

`a = (Delta v)/(Delta t)`

where   `a` - acceleration      

         `Delta v` - change in velocity and

         `Delta t` - change in time

In the above problem, initial velocity is...

initial velocity u = 0

final velocity v=30 m/sec

time taken=20 seconds

acceleration = final velocity -initial velocity/total time taken

after calculations the final answer comes to 1.5m/sec square
