To find the speed acquired by a given body after 0.5 minutes of movement, we apply the formula: V = Vн + a * t.
Variables: Vн – initial speed (Vн = 18 km / h = 5 m / s); a – acceleration (a = 0.2 m / s2); t – duration of movement (t = 0.5 min = 30 s).
Calculation: V = Vн + a * t = 5 + 0.2 * 30 = 11 m / s.
Answer: In 0.5 minutes, the given body will acquire a speed of 11 m / s.
