Answer to Question #247477 in Mechanics | Relativity for asdfg

Question

1. Angelo Jogged 10 times in 30 mins around the track with a radius of 50m. find his average speed and average velocity.

Answer 1

$\text{Distance jogged=}10\times{2\pi\times{50}}=3142m\\ time=30mins=1800s\\ \text{Average speed=}\dfrac{Distance}{Time}=\dfrac{3142}{1800}=1.75ms^{-1}$$Displacement=0m\\ Velocity=\dfrac{Displacement}{Time}=0ms^{-1}$
