Question

an athlete runs on a circular track of radius 50 m with a constant speed .It takes 50 seconds to reach point B starting from A find distance displacement speed

Answer 1

Distance = 315m (appox.)

Displacement = 0m

Speed = 315m (approx.)/50s = 6.3m/s

Answer 2

Distance(d) = 315m

Displacement(s) = 0m

$speed = \frac{315}{50} = 6.3 \frac{m}{s}$

hope it is usefull
