what is the velocity of the ball after 8.5 seconds?

how far does the ball roll in 10 seconds?

any one can help pleasse im stuck

show n detail how to find the answer

- physics rewrite -
**Damon**, Sunday, January 13, 2008 at 3:45pmv = Vo + a t

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

here

Vo = initial velocity = 0

Xo = initial position = 0

a = 2

t=8.5 in part 1 (first equation for v)

t = 10 seconds for part 2 (second equation for x)

try it from there
