The racing car, when starting off, managed to reach a speed of 90 km / h in 3 s. What path does the car travel during this time?
Problem data: V0 (initial speed of a given racing car) = 0 m / s (the car was moving away); V (reached speed) = 90 km / h (in SI V = 25 m / s); t (racing car acceleration time) = 3 s.
The path covered by a given racing car in 3 s is determined by the formula: S = (V + V0) * t / 2.
Let’s calculate: S = (25 + 0) * 3/2 = 37.5 m.
Answer: In 3 seconds, a given racing car has traveled 37.5 m.
