A rod `AB` length `5 m` which remains in vertical plane has its ends `A` and `B` constrained to remain contact with a horizontal floor and a vertical wall respectively. Determine the velocity of the end `B` and angular velocity at the position shown in Fig. , if the point `A` has a velocity of `3ms^(1)`rightward.

Explanation

Velocity of end `A vecv_(A)` is horizontal while velcity of the end `B, vecv_(B)` is vertical downward. For finding the positin of instntanneous centre of rotation. Drop perpendicular to the directins of `vecv_(A)` and `vecv_(B)` at points and `B` respectvely. The intersection point `I` be the instantaneous centre.
For the end `A, v_(A)=omega(IA)`
`:. omega=(v_(A))/(OA)=2/(5sin37^@)=3/3=1rads^(-1)`
For the end `B, v_(B)=omega(O'B)-1xx5xxcos37^@=4ms^(-1)`
