1.	From the given figure if speed of end B of rod of length 4 m at an instant when θ=30∘ is 4 m/s then angular velocity of rod is. [angle between wall is 135∘] Write upto two digits after the decimal point. (Take cos15=√3+12√2 and √3=1.7)
Answer» From the given figure if speed of end B of rod of length 4 m at an instant when $θ = 30^{\circ}$ is 4 m/s then angular velocity of rod is. [angle between wall is $135^{\circ}$ ] Write upto two digits after the decimal point. (Take $cos 15 = \frac{\sqrt{3} + 1}{2 \sqrt{2}}$ and $\sqrt{3} = 1.7$ )
