Question

1. A sprinter races in the 100 meter dash. It takes him 10 second to reach the finish line

What is his average velocity?

Answer 1

v = 10 m/s

Step-by-step explanation:

Given that,

Distance covered by a sprinter, d = 100 m

Time taken by him to reach the finish line, t = 10 s

We need to find his average velocity. We know that velocity is equal to the distance covered divided by time taken. So,

v = d/t

`v=(100\ m)/(10\ s)\\\\v=10\ m/s`

Hence, his average velocity is 10 m/s.
