Question

An object moving in a circular path of diameter 200m in time 2 mins. Calculate the speed of the object.

PLEASE HELP...

​

Answer 1

speed-->d/t-->200÷120mins-->1.66m/s

Answer 2

Angular Speed =w= 2πn = 2π1/T

= 2×3.14× 1/120

= 6.28/120

= 0.052333 rad/s

So, Linear Speed = v = rw

v = 100×0.052333

v = 5.2333 m/s.....●
