Question

two particles A and B are connected by a rigid rod AB . the rod slides along perpendicular rails . the velocity of A to the left is 10m/s. what is the velocity of b when angle between A and the rod is 600.

Answer 1

Here we have given, two particles A and B which are connected by a rigid rod AB, which makes an angle 60° at A.

                  Velocity of A to the left = 10 m/s.

                                          Angle α = 60°

                    Velocity of B = Need to calculate.

Since particle B is moving upwards with velocity V.

So,  

                                           tan 60° = $\frac{v}{10}$

                                          v = $\sqrt3 \times 10 = 17.3 m/s$
