Question

point AB is pinned to the slider B. The wheel is fixed. The wheel has a radius r=0.6m and the link AB of length L=3m. currently, the slider is sliding along the horizontal track with a cinstant velocity vb= 6m/s.

What is the angular velocity of the wheel and of link AB.

What is the velocity of point A.

What is the angular accelearation, magnitude and direction, of the wheel and of link AB.

What is the acceleration of point A.
