Suppose a dog is chasing a rabbit along the y-axis, and the coordinate of the rabbit's position at time t is given by (1/3) t^2 +4t. The dog's speed is equal to one half the distance between the two animals and the dog's coordinate at t=0 is y=-5.
a. Determine a differential equation for the position of the dog
b. Justify whether the dog will ever catch the rabbit?
