Сравнив данные уравнения с общим видом уравнения координаты:

x = x(0) + υt + at²/2,

приходим к выводу, что движение тела является прямолинейным, равномерным. Составляющие вектора скорости υ по значению равны:

υ(х) = -2 м/с

υ(y) = 2 м/с

По модулю скорость υ равна:

υ = √(υ(х)² + υ(y)²) = √((-2)² + 2²) = √8 = 2,8284... = 2,83 м/с

Ответ: 2,83 м/с.
