25s after the start of the movement, the speedometer showed a speed of 36 km / h. Determine the acceleration of the vehicle.
v1 = 0 m / s – initial vehicle speed;
v2 = 36 km / h = 10 m / s – vehicle speed by time t;
t = 25 s – time.
It is required to find the acceleration of the car a m / s ^ 2.
a = (v2 – v1) / t = (10 – 0) / 25 = 0.4 m / s ^ 2.
