1. The problem statement, all variables and given/known data Particle has two displacements. 1 - 11m, 89 degrees 2 - ? 1+2 - 8.6m, 129 degrees So: 1 = (11, 89°) 2 = ? 1+2 = (8.6, 129°) 2. Relevant equations X-component = M x cos(Θ) Y-component = M x sin(Θ) Total magnitude = sqrt((total x-component)² + (total y-component)²) Total angle = tan-1 (total y-component / total x-component) 3. The attempt at a solution I'm not terribly sure how I should best try to find the magnitude and angle of the second portion of the movement here. I would've tried to solve for total magnitude, but I'm missing both X and Y components for #2, so... what should I do?
