These tasks: the car started to move (V0 (initial speed) = 0 m / s); t (acceleration duration) = 2 min (120 s); V (the speed that the car in question gained) = 72 km / h (20 m / s).
The acceleration of the car is determined by the formula: a = (V – V0) / t = V / t.
Calculation: a = 20/120 = 0.167 m / s2.
Answer: Auto acceleration is 0.167 m / s2.
