A blue bird and a red bird are initially sitting atop two

 different trees while a hunter (represented by the arrow) is watching them 

A blue bird and a red bird are initially sitting atop two different trees while a hunter (represented by the arrow) is watching them from below. The hunter only has 1 arrow and needs to shoot both birds at the same time. If at time t = 0 both birds take off from the treetops: The first bird has an initial velocity in the x-direction of Voix and a constant acceleration in the x-direction of ax and the second bird has an initial velocity in the negative x-direction of vozx and an acceleration in the x-direction. Also, both birds have neither acceleration or initial velocity in the y-direction. Assuming that the speed of the arrow is such that when it is fired it moves in a straight line (i.e. you can neglect gravity) and it will strike both birds simultaneously: 2 Xol V10 a 2 Xo2 az 8 a) Plot the position in the x-direction as a function of time for both birds on the same co-ordinate system (the plots do not have to be exact). b) Write down the equations of motion in x and y directions for bird 1. c) Write down the equations of motion in the x and y directions for bird 2. d) Using 7 (t) and 2 (t) to represent the position vector of birds 1 and 2, respectively, write down the components of the position vector for both birds in parenthesis (vector) format. e) Write an equation using the tangent of the position vectors that describes when the hunter should release the arrow. f) Solve this equation for the time at which the hunter should release his arrow (Note that you will be solving a quadratic equation and will therefore get 2 answers). g) What is the physical significance of the 2 answers?
