What is the modulus of movement of the car in 2 minutes, if during this time its speed has changed from 0 to 72 km / h?

These tasks: t (duration of movement of the car) = 2 min (in SI t = 120 s); V0 (initial speed) = 0 m / s; V (speed at the end of travel) = 72 km / h (in SI V = 20 m / s).
The module of movement of the car during its uniformly accelerated movement is calculated by the formula: S = (V + V0) * t / 2.
Let’s calculate: S = (20 + 0) * 120/2 = 1200 m (1.2 km).
Answer: The vehicle movement module is 1.2 km.
