Multiplicamos la primera ecuación por 2 para simplificar y restamos: Primera multiplicada: (-20 = -6a + 2b) Segunda: (2 = 5a + 2b)
Las componentes de un vector velocidad son ( v_x = -5 ) m/s y ( v_y = -5\sqrt3 ) m/s. ¿Cuál es la rapidez (módulo) y en qué dirección se mueve el objeto?
(w_x = 10 \cos 210^\circ) (\cos 210^\circ = \cos(180^\circ + 30^\circ) = -\cos 30^\circ = -\frac\sqrt32) So (w_x = 10 \cdot \left(-\frac\sqrt32\right) = -5\sqrt3)
