If an arrow is shot upward on mars with a speed of 54 m/s, its height in meters t seconds later is given by
y = 54t − 1.86t2.
(round your answers to two decimal places.)
(a) find the average speed over the given time intervals.
(i) [1, 2]
m/s

(ii) [1, 1.5]
m/s

(iii) [1, 1.1]
m/s

(iv) [1, 1.01]
m/s

(v) [1, 1.001]
m/s

(b) estimate the speed when t = 1.
m/s
