A rigid rod (AB) of length L = √2 m is undergoing translational as well as rotational motion in the x-y plane (see the figure). The point A has the velocity V1 = i + 2j m/s. The end B is constrained to move only along the x direction.
The magnitude of the velocity V2 (in m/s) at the end B is __________.
-
- 3m/s
- 2m/s
- 4m/s
- 1m/s
Correct Option: A
V1 = i + 2j
|V1| = √2² + 1² = √5
By drawing velocity diagram
| α = tan-1 |  | 2 |  | = 63.44 | ||
| 1 |
By applying sine rule
| = | sin 45 | sin 71.57 |
∴ V2 = 3 m/sec
