Find the acceleration of A at the instant shown. Indicate the direction with the sign based on the axes in the figure. Express your answer to three significant figures in meters per second squared.

 
Learning Goal:
To be able to use the equation for relative acceleration between
two points to find unknown linear accelerations and angular
accelerations of connected bodies.
Member ABC is controlled using a rack and pinion, which is
connected at B. (The rack is the long, horizontal gear.) The rack
can only move horizontally and the pinion does not translate. A
block in a sleeve is connected at A and allows movement only
in the vertical direction. Member ABC has a total length of
2.40 m and the distance between A and B is 1.25 m. When
member ABC forms an angle of 0 = 37.0° with the rack, the
acceleration of B is aß = 1.55 m/s² and the velocity of the
block attached at A is v₁ = 2.95 m/s in the direction shown.
Positive angular velocity and acceleration are in the
counterclockwise direction. (Figure 1)
