# Inclined Plane and soccer ball

i think this is an easy question but i forgot how and the book doesn't want to tell me. can anyone tell me how to figure this out? thanks.

A soccer ball is released from the top of a smooth incline. After 4.58 s the ball travels 10.8 m. One second later it has reached the bottom of the incline.

(question 1)Assume the ball's acceleration is constant and determine its value ( m/s2).

(question 2)How long is the incline?

1)
what's the initial velocity?

how much time has elapsed?

what is the displacement of the ball?

That's three things you know. What formula relates these three things along with acceleration?

thats the only information included in the question.

$$s = \frac{1}{2} a t^2$$

then you should be fine with both questions...
good luck :)
