1. [8] At a given instant of time t, measured in seconds, the horizontal position of the airplane shown below is given by x = 215/2, where x is measured in meters. If the equation of the path is y = x2/5, also measured in meters, determine the velocity and acceleration of the airplane when t = 2 s. Express your answer in terms of the magnitude of the velocity and the angle between the velocity and positive x-axis, and likewise for the acceleration
