Question

You are training to run the 100 m race at a track and field meet.You time yourself and find you can run it in 10 seconds. How fast are you abke to run it

Answer 1

Answer:

$10\ \text{m/s}$

Explanation:

$s$ = Displacement = $100\ \text{m}$

$t$ = Time taken = $10\ \text{s}$

Velocity is given by

$v=\dfrac{s}{t}\\\Rightarrow v=\dfrac{100}{10}\\\Rightarrow v=10\ \text{m/s}$

The person is able to run at a speed of $10\ \text{m/s}$ in order to complete the race in the given time.
