Question

two racing car of mass m1 and m2 are moving circles of radii r and 2r respectively and their angulars speed are equal.The ratio of time taken cars t1:t2 to complete one revolution is​

Answer 1

Answer:

hi.

Explanation:

The angular speed ω=

t

2π

Now, Angular speed of first car ω

1

=

t

2π

Angular speed of second car ω

2

=

t

2π

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

ω

2

ω

1

=

t

2π

t

2π

ω

2

ω

1

=

1

1

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