If a rock is thrown vertically upward from the surface of Mars with velocity of 20 m/s, its height (in meters) after t seconds is h = 20t - 1.86t². (a) What is the velocity (in m/s) of the rock after 2 s? 12.56 m/s (b) What is the velocity (in m/s) of the rock when its height is 30 m on its way up? On its way down? (Round your answers to two decimal places.) X m/s 9.32 -9.32 X m/s up down
