Distance, Acceleration and Time Question

[student34]

Homework Statement

If you are in a helicopter and the helicopter lifts off at a constant acceleration of 5.0m/s^2 for 11.0 seconds, what is the total distance traveled from the ground?

Homework Equations

y = yo + voyt + 1/2*ax*t^2

The Attempt at a Solution

y = 0 + 0 + 1/2(5m/s^2)(11^2)

y = 3*10^2m

But, apparently the actual answer is 4.6*10^2m.

Check your arithmetic.


Added in Edit:

Guess I have to check mine too :(

I'll check mine instead !

DOH !
