For a short time, gear A of the automobile starter rotates with an angular acceleration of a = (50w¹/2) rad/s², where w is in rad/s. (Figure 1) Figure 1 of 1 > Part A Determine the angular velocity of gear B after gear A has rotated 50 rev, starting from rest. The radii of gears A and B are 10 mm and 25 mm, respectively. Express your answer to three significant figures and include the appropriate units. ? I μA WB = Units Value

For the mechanism in the image below, the end A of the bar is moving downward along the slotted guide with a constant velocity va = 2.1 m/s. If r = 0.5 m, determine the angular velocity W of bar AB when 0 = 38°. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. A A ω, α y В
