AN initially stationary cart rolls down an incline with a measured acceleration of 2.7m/s^2. How far along the incline does the cart roll in 3.1s?
I used the equation delatx=1/2(2.7m/s)(-3.1s) and my answer was 4.2m. Is this correct?
Any help is greatly appreciated. ^_^ Thanks!

a= 2.7; t =3.1; u =0
s = ut + 0.5 * at^2
s = 0 + 0.5 * 2.7 * 3.1^2
answer
note: there is no negative sign of - 3.1s in your answer
s = ut + 0.5 * at^2
s = 0 + 0.5 * 2.7 * 3.1^2
