Answer:
Speed, S of Carl Lewis is 33.074ft/s.
Explanation:
Given the following data;
Distance, d = 100m
Time, t = 9.92secs
Speed =?
Speed can be defined as the rate of change in distance with time. Speed is a scalar quantity and as such it has only magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex]
[tex]S = \frac{d}{t}[/tex]
Substituting into the above equation;
[tex]S = \frac{100}{9.92}[/tex]
Speed, S= 10.081m/s
Now to convert to feet (ft);
We know that 1 metre (m) = 3.28084 feet (ft).
Therefore, 10.081m/s = 10.081 * 3.28084ft/s
This is equal to 33.074ft/s.
