| In this problem, we are dealing with uniformly accelerated rectilinear motion,
then the displacement can be calculated by the formula S = V0 * t + 1/2 * a * t ^ 2, where V0 is the initial speed, a is the acceleration, and t is the time.
Since the car starts to move, then V0 = 0, then S = 1/2 * a * t ^ 2.
Let’s substitute our values:
S = 1/2 * 2 * 6 ^ 2 = 36 (m).
The equation of speed of rectilinear uniformly accelerated motion can be found as a derivative of the equation of displacement, then V = (V0 * t + 1/2 * a * t ^ 2) ‘= V0 + a * t.
Substitute the values: V = 0 + 2 * 6 = 12 (m / s), that is, the speed of 12 (m / s) will pick up the car in 6 seconds.
Answer: 36 (m), 12 (m / s).
