Suppose that the position of one particle at time t is given by and the position of a second particle is given by (a) Graph the paths of both particles. How many points of intersection are there? 2 2 points of intersection (b) Are any of these points of intersection collision points ? In other words, are the particles ever at the same place at the same time? If so, find the collision points. (Enter you answers as a comma-separated list of ordered pairs. If an answer does not exist, enter DNE.) x 1 = 3 sin( t ), y 1 = 2 cos( t ), 0 ≤ t ≤ 2 π x 2 = − 3 + cos( t ), y 2 = 1 + sin( t ), 0 ≤ t ≤ 2 π . Yes No
