Question

The speed s in m/s of an athlete can be modeled by the

function
s = 9.8 – 9.8e-0.88t
where t is the time (in seconds) after the
athlete starts running. Graph this model and use the graph to
estimate the speed of the athlete 2 seconds after his launch.
Round your answer to the nearest whole m/s.
speed m/s

Answer 1

Step-by-step explanation: The equation is s = 9.8 – 9.8e-0.88t and we need to find the speed if t or time = 2 so to solve this equation algebraically you would;

`s = 9.8-9.8e-0.88(2)`

`s = 9.8-9.8e-1.76`

`s = 8.04-9.8e`

and after graphing it you would get

`-18.5991619189`

which after rounding and using absolute value would be

`s=18.6`
