## Homework Statement

A sled starts from rest at the top of a hill and slides down with a constant acceleration. At some later time the sled passes a red flag stuck into the snow at an unknown distance from the top of the hill; 2.00 s after passing the red flag the sled is 17.83 m past the red flag; and another 2.00 s later, the sled is now 42.27 m past the red flag.

What is the acceleration of the sled?

What is the speed of the sled when it passes the red flag?

How much time did it take for the sled to go from the top to the red flag?

How far did the sled go during the 1st second after passing the red flag?

How far did the sled go during the 2nd second after passing the red flag?What is the distance from the top of the hill to the red flag?

## Homework Equations

constant acceleration --> x(t) = x + (v)(t) + 1/2(a)(t^2)

d = vi(t) + 1/2(a)(t^2)

## The Attempt at a Solution

First i need to find the acceleration of the sled.

Would i set it up as 47.27-17.83 = (0)(2) + 1/2(a)2^2

so a = 14.72 m/s ???? is that correct?

any help would be greatly appreciated. thank you
