Correct, you mean we can use the equation s = ut + (at^2)/2 because we now have the acceleration. Try it out , you'll see that it will give you the same answer. However in this case, it is important to first work with what has been given in the data before using what was found or calculated.

Thanks a lot you are really helping
Glad to hear that
At question 5b (2)I thought of using this formula
S=UT+2AT cause we have acceleration
