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
