The car moves on a horizontal road evenly at a speed of 10 meters per second. at the beginning of one of the straight sections with a length of 525 meters, the driver turned on another gear, as a result, at the end of this section, the car’s speed increased to 25 meters per second. Find the acceleration of the car in this section.
Let us consider the movement of the car exactly in the area where acceleration occurs. Let us assume that the acceleration is the same throughout the entire section, therefore, the motion is uniformly accelerated.
S = (V ^ 2-V0 ^ 2) / 2a
a = (V ^ 2-Vo ^ 2) / 2S = (625-100) /1050=0.5m/s^2
