2. Camille launches a model rocket In an open field near her house. The rocket has a bit ofa problem, being slightly off balance. Its trajectory Is described by the function y = 601n(x + 1) (iv for O 5 x 5 36.15, where y is the rocket's height (in feet) above the ground, and x is the horizontal distance (in feet) between the launch site and a point directly below the rocket. Below is a graph of the trajectory of the rocket: 8U isLl 4U B. Given that the rocket's horizontal velocity (%) i5 50 isec when it's directly over a point 20 (horizontal) feet from the launch site, determine the rocket's vertical velocity (1%) at that point
