A graphing calculator is recommended. If a rock is thrown upward on the planet Mars with a velocity 8 m/s, its height in meters t seconds later is given by y = 8t-1.862. (Round your answe (a) Find the average velocity (in m/s) over the given time intervals. (0) [1, 2] () [1, 1.5) () [1, 1.1] (iv) [1, 1.01] (v) [1, 1.001] m/s m/s m/s m/s. m/s. (b) Use your answers from part (a) to estimate the instantaneous velocity of the rock (in m/s) when t 1. m/s
