Predict the change in a runner’s finishing time with a wind speed of 5meters/second.
Accepted Solution
A:
Answer:t = -1.24Step-by-step explanation:From the equation;t = 0.0119s² - 0.308 s -0.0003 Where t is the change in a runner's performance, and s is the tail wind speed.But s = 5 m/sTherefore;t = 0.0119 (5²) - 0.308(5) -0.0003 = 0.2975 - 1.54 - 0.0003 = - 1.2428 Since, negative means a runner finishes with a lower time, then; t = -1.2428 to the nearest hundredth = -1.24
