Problem

Three particles move on a horizontal plane with the following velocities: v⃗A=30 m s−1\vec v_A = 30\,\text{m\,s}^{-1} due east, v⃗B=20 m s−1\vec v_B = 20\,\text{m\,s}^{-1} at 30∘30^\circ north of east, and v⃗C=25 m s−1\vec v_C = 25\,\text{m\,s}^{-1} due south. (a) Find the velocity of A relative to B, expressing your answer as magnitude and direction. (b) Find the velocity of B relative to C. (c) Using your results, obtain the velocity of A relative to C.
