Question

Ques no. 23 : Two racing cars of
masses and are moving in circles
of radii r1 and r2 respectively. Their
speeds are such that each makes a
complete circle in the same
duration of time t. The ratio of the
angular speed of the first to the
second car is

Answer 1

Explanation:

Given that, both the cars complete on circle in the same time t

We know that,

The angular speed ω=t2π

Now, Angular speed of first car ω1=t2π

Angular speed of second car ω2=t2π

Therefore, the ratio of angular speed of the first car to that of second

  ω2ω1=t2πt2π

 ω2ω1=11

Hence, the ratio of angular speed of the first car to that of second is 1:1.
