Question

if a person is moving in a circular track of radius 2m he completes 11 rounds for each round the person takes 10 secs. find the average speed and average velocity​

Answer 1

Answer:

we know that Speed(v)= (Distance/Time)

Here, Distance= Circumference of the circular path = 2* pi * r = 2*3.14*2 = 12.56 m

and, Time = 2 Sec

This gives, Speed(v) = (12.56/2) = 6.23 m/sec.

Further, Angular speed can be found as

Angular Speed(w)=v/r=6.23/2=3.115 rad/s

Hope it helps!
