11) The two ends A and B of a uniform rod of length L = 1 and mass m are moving with velocities vA and vB as shown. The angular velocity of the rod is. a ) 20 r a d / s b ) 25 r a d / s c ) 30 r a d / s d ) 50 r a d / s Share with your friends Share 29 Sanjay Singh answered this Dear student Let the line joining A to B be X axis and Y axis is perpendicular to the X axis.Velocity of point A with respect to B along the line joining A and B is zero.Velocity of A along X axis towards B is VAX=20cos53°=20×35=12m/sVelocity of B along X axis towards A is VBX=Vcos37°=V×45m/s12=V×45V=5×124=15m/sAngular velocity of rod is ω=Velocity of point A with respect to B in the direction perpendicular to the line joining A and B Separation between A and BVelocity of A perpendicular to the line joining A and B is VAY=20sin53°=20×45=16m/sVelocity of B perpendicular to the line joining A and B is VBY=15sin37°=15×35=9m/sω=16+91=25rad/sRegards 47 View Full Answer Apoorv Tyagi answered this What is the value of vb? -15 Rashmika B answered this only va is given as 20 m/s -16 Rashmika B answered this but the answer is 25 rad/s...how's that? -19
