I've tried for hrs to figure this out please someone help

Here is a tip for doing any of these kinematics questions.
1) write down a
complete list of variables  just use the symbols (I have defined them this time for your benefit)
u = initial velocity
v = final velocity
s = distance travelled
t = time taken
f = acceleration
2) Place all the information given in the question against your list.
u = 0
v = (290*1000)/3600 metres per second (did you notice this trap?)
s = 2770
t = ?
a = ?
3) Now write down all the kinematics equations you know (you shouldn't have more than five)
I will only write down 1 to start you off
v^2 = u^2 + 2fs
