Starting off, the car moved for 25 s with a constant acceleration of 0.45 m / s. what path he traveled and what speed he gained during this time.
t = 25 seconds – vehicle movement time;
a = 0.45 m / s2 – vehicle acceleration.
It is required to determine the path S (meters) traveled by the car and its speed at the end of the path v (m / s).
By the condition of the problem, the car started moving without initial speed (v0 = 0). Then, the path traveled by the car will be equal to:
S = a * t ^ 2/2 = 0.45 * 25 ^ 2/2 = 0.45 * 625/2 = 281.25/2 = 140.625 meters.
Vehicle speed will be equal to:
v = a * t = 0.45 * 25 = 11.25 m / s.
Answer: the car traveled a distance of 140.65 meters, its speed at the end of the route was 11.25 m / s.
