Please answer the questions A,B and C. Thanks

Learning Goal: To be able to use the equation for relativo acceleration between two points to find uniknown linear acoelerabons and angular accelerations of connected bodies. Member ABC is controled 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 2.30m and the distance between A and B is 1.15m. When member ABC forms an angle of =33.0 with the rack, the acceleration of B is aE=1.75m/s2 and the velocity of the block attached at A is vA=2.55m/s in the direction shown. Positive angular velochy and acceleration are in the counterclockwise direction. Find the acceleration of A at the instant shown. Indicate the drection with the sign based on the axes in the figure. Express your answer to three significant figures in meters per second squared. Part B-Acceleration of C Find acceleration of C,aC, at the instant shown. Give your answer in componert form. Express your two answers, separated by commas, to three significant figures in meters per second squared. Find the acceleration of 8 when the acceleration of C is aC=4.75i+3.00jm/s2 and the acceleration of A is aA=3.00Jm/s2. Member ABC makes an angle of =23.0 at the instant considered. Express your answer to three significant figures in meters per second squared
