Question

A van traveling down a slope with a uniform acceleration of 2.15 meters/second2 attains a speed of 20.00 meters/second after 7.00 seconds. What is the initial velocity of the van?

Answer 1

if memory serves, the formula vf^2 = vi^2 + 2at

Answer 2

use it...\[v=u+a t\]
v=final velocity
u = initial velocity
a=acceleration
t=time

Answer 3

lol, soo close

Answer 4

i believe mine is for the change in distance, not the time

Answer 5

v^2=u^2+2ad

Answer 6

yeah, that one :)

Answer 7

thanks!
