CBSE Class 9 Answered
Two racing cars of masses m1 and m2 are moving in circles of radii r1 and r2 respectively.
Their speeds are such that each makes a complete circle in the same length of time t.Find the ratio of angular speed of the first car to that of the second car is.

Expert Answer
Angular velocity is the rate of change of angular displacement with time.
Given that both the cars complete one circle in the same time 't'
Angular speed of first car,ω1 = 2π / t
Angular speed of the second car, ω2 =2π /t
Therefore the ratio of angular speed of first car to that of second,
The ratio of angular speed of first car to that of second =1:1
