Question

Angular velocity of a car turning of 100 m radius is 0.1 rad/sec. Find the linear velocity of the car.
1. 360 kmph
2. 36 kmph
3. 3.6 kmph
4. 0.36 kmph

Answer 1

Correct Answer - Option 2 : 36 kmph

Concept:

If the angular velocity is 'ω' and turning radius is 'r' then,

Linear velocity is given by v = ω × r

Calculation:

Given:

ω = 0.1 rad/sec, r = 100 m.

v = ω × r

v = 100 × 0.1

v = 10 m/s = 36000 m/hr = 36 kmph
