If an arrow is shot upward on Mars with a speed of 52 m/s, its height in meters t seconds later is given by y = 52t-1.862. (Round your answers to two decimal places.) (a) Find the average speed over the given time intervals. (0) [1, 2] 52.42 x m/s (ii) [1, 1.5] 53.35 x m/s (iii) [1, 1.1] 54.094 x m/s (iv) [1, 1.01] 54.28 * m/s (v) [1, 1.001] 54.28 x m/s (b) Estimate the speed when t = 1. 54.28 m/s
