. Determine the direction of the crate’s velocity at this instant. B. Determine the magnitude of the crate’s acceleration to this instant

The cable at end B of the slender rod shown below is replaced with a linear actuator that commands end B to move toward the vertical wall with a constant speed vB = 0.01 ft/s.  Determine the angular velocity and angular acceleration of the beam at the instant when end B begins to move. At this instant, B is a distance d = 10ft away from the vertical wall.  Determine algebraic expressions for the angular velocity and angular acceleration of the beam at the instant when end B has moved a distance xB. Use the given notation and no numerical values. After determining the algebraic expression for computing a quantity, do not substitute the quantity with this expression in subsequent derivations.  Use Matlab to compute the angular velocity and angular acceleration of the beam at every instant when end B has traveled another sB = 0.1 ft toward the vertical wall, until end A reaches the vertical wall.
