A robotic vehicle, or rover, is exploring the surface of Mars. The stationary Mars lander is the origin of coordinates, and the sur- rounding Martian surface lies in the xy-plane. The rover, which we x = 2.0 m - 10.25 m > s22t2 represent as a point, has x- and y-coordinates that vary with time: y = 11.0 m > s2t + 10.025 m > s32t3 (a) Find the rover’s coordinates and distance from the lander at t = 2.0 s. (b) Find the rover’s displacement and average velocity vectors for the interval t = 0.0 s to t = 2.0 s. (c) Find a general S. Express expression for the rover’s instantaneous velocity vector v S at t = 2.0 s in component form and in terms of magnitude and v
