Calculus I (Related Rates) A particle on the x-axis is moving to the right at 2 units per second. A second particle is moving down the y-axis at the rate of 3 units per second. At a certain instant the first particle is at the point (5,0), and the second is a the point (0,7). How rapidly it the angle between the x-axis and the line joining the two particles changing at that instant? Are the particles moving towards or away from each other at that instant?
