Question

Zafar starts running along a circular path of radius 100 m for his morning exercise. What is his average velocity at the end of one lap if he takes 5 minutes to complete one lap? ​

Answer 1

Average velocity at the end of one lap if he takes 5 minutes to complete one lap is $\underline{\sf{0,33 \: m/s }}$

EXPLANATION

Formula of Velocity :

$\underline{\boxed{\sf{v = \frac{r}{t} }}}$

• v = velocity (m/s)
• r = radius (m)
• t = tempo (s)

.

We Know

• r = 100 m
• t = 5 minutes = 5 × 60 s = 300 s

.

Question

• v = ...?

.

Answer

$\sf{v = \frac{r}{t} }$

$\sf{v = \frac{100 \: m}{300 \: s} }$

$\sf{v = 0,33 \: m/s }$

• note : I used MKS system

.

Hence, average velocity at the end of one lap if he takes 5 minutes to complete one lap is 0,33 m/s
