he motor turns gear A with an angular acceleration of αA=2⁢ rad/s^2 when the angular velocity is ωA=20 rad/s, determine the angular acceleration and angular velocity of gear D

The slotted arm is pivoted at 0 and carries the slider C. The position of C in the slot is governed by the cord which is fastened at D and remains taut. The arn turns counterclockwise with a constant angular rate 8= 4 rad/sec during an interval of its motion. The length DBC of the cord equals R, which mnakes r - 0 when 8 =0. Determine the magnitude a of the acceleration of the slider at the position for which 8=30°. The distance R is 15 in. R. B.

A motor gives gear A an angular acceleration of a A = (2+³) rad/s², where t is in seconds. (Figure 1) = Figure αB 175 mm 100 mm 1 of 1 αA WA Part A If this gear is initially turning at w = 19 rad/s, determine the angular velocity of gear B when t = 3 s, measured counterclockwise. Express your answer in radians per second to three significant figures. Enter positive value if the angular velocity is counterclockwise and negative value if the angular velocity is clockwise.
