The table shows the position of a motorcyclist after accelerating from rest. t (seconds) 0 2 3 4 5 6 s (feet) 49 10.6 23.1 50.3 109.4 238.1 (a) Find the average velocity (in ft/s) for each time period. (1) [2, 4] ft /s (11) [3, 4] ft/s (11i) [4, 5] ft/s (iv) [4, 6] Ift /s (b) Plot the points in the table to create a graph of s as a function of t to estimate the instantaneous velocity (in ft/s) when t = 3. (Round your answer to one decimal place.) ft/s Need Help? Watch It
