Question

An athlete sprinter 50m in 9.2 seconds, and then walks slowly back to the starting line in total time of 54 seconds. (Assume he runs in the positive direction.)What is his average velocity during the sprint?

Answer 1

Answer:

The average velocity during the sprint is 5.43 m/s.

Explanation:

Given that,

Distance = 50 m

Time = 9.2 sec

Total time = 54 sec

We need to calculate the average velocity during the sprint

Using formula of average velocity

$v=\dfrac{D}{T}$

Where, D = total displacement

T = total time

Put the value into the formula

$v=\dfrac{50}{9.2}$

$v=5.43\ m/s$

Hence, The average velocity during the sprint is 5.43 m/s.
