A wheel of radius r rolls without slipping on a horizontal surface shown below. If the velocity of point P is 10 m/s in the horizontal direction, the magnitude of velocity of point Q (in m/s) is _____.

1. 20m/s
2. 19m/s
3. 21m/s
4. 10m/s

Correct Option: A

Vp = r ω = 10 m/s
Vq = 2 r ω = 2 × 10 = 20 m/s
