while driving his sports car at 20.0 m/s down a four-lane highway, eddie comes up behind a slow-moving dump truck and decides to pass it in the left lane. If eddie can accelerate at 5.00 m/s2) (squared) how long will it take for him to reach a speed of 30.0 m/s?

vfinal=vinitial + acceleration*time
solve for time.
solve for time.

v = 30m/s u = 20m/s a = 5m/s2 t = ?
v = u + at
30 = 20 + 5*t
30-20 = 5t
10 = 5t
10/5 = t
t=2s
v = u + at
30 = 20 + 5*t
30-20 = 5t
10 = 5t
10/5 = t
t=2s

Given : a = 5.00 m/s^2
vi = 20.0 m/s
vf = 30.0 m/s
Unknown: delta(t)
equation: a = (vf - vi) / delta(t)
solve: delta(t) = 10m/s / 5m/s^2 = 2 secs
vi = 20.0 m/s
vf = 30.0 m/s
Unknown: delta(t)
equation: a = (vf - vi) / delta(t)
solve: delta(t) = 10m/s / 5m/s^2 = 2 secs
