Answer to Question #161365 in Molecular Physics | Thermodynamics for Samir khan

Question

Resolve the following vectors into their components:

a)7.5m/s2 [NW] b)15m/s[25*WofS]

Answer 1

a)

$$a_x=7.5cos\theta, a_y=7.5sin\theta.$$

b)

$$v_x=15cos(180^{\circ}+25^{\circ})=-13.59\ \dfrac{m}{s},$$ $$v_y=15sin(180^{\circ}+25^{\circ})=-6.34\ \dfrac{m}{s}.$$
