I'm stuck on which eqaution I need to use for this.

- Physics -
**Damon**, Monday, January 14, 2008 at 8:01pmconstant acceleration means

v = Vo + a t

We know Vo (convert it from km/hr to meters/second)

We know a = -34(9.8)

set v = 0, we stopped and solve for t, time spent deaccelerating in the hay

then

x = Xo + Vo t + (1/2) a t^2

here x is unkown

call Xo = 0 start of deacceleration

we know Vo and t and a from above

solve for x, distance through hay
