Answer 1

Explanation:

If you are having trouble visualizing . Assume only one rod moving so point will slide through second rod with velocity u .

Since both rods are moving so velocity will be resultant of two velocity vectors of magnituder u at 106° .

$resultant = \sqrt{ {u}^{2} + {u}^{2} + 2(u)(u) \cos(106) } \\ = 2u \sqrt{1 + \cos(106) } \\ = 2u \sqrt{2 \cos {}^{2} (53) } \\ = 2 \times 1.41 \times 0.60 \times u \\ = 1.69u$

53 , 37 and 90 is 3-4-5 side right angle triangle
