Answer:

Using the standard equations of motion we know:

Dist(x)= Initial Velocity x Time + 1/2 Constant Acceleration x Time^2 (Squared)

We know the Initial Velocity (12 .0 m/s) and the Constant Acceleration (-0.6 m/s/s negative for deceleration) but not the time.

But we also know:

Change in Velocity (∆V) = Acceleration x Time (at)

So

∆V = 12 m/s - 0 m/s = a x t = 0.6 m/s^2 x t

Solving for t = (12 m/s)/(0.6 m/s/s) = 20 s

Plugging that into equation 1:

Dist = 12 m/s x 20 s + 1/2 (-0.6m/s/s) x (20 s)^ 2 = 240 m - 120 m = 120 m to stop
