5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity w and angular acceleration a (both counterclockwise). 3) if W = 5.5 rad/s and a = 7.5 rad/s², what is the magnitude of the linear acceleration of point A in m/s? Hint, don't forget linear acceleration has two components, normal and tangential. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. 0.5 m 0, a

5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity W and angular acceleration a (both counterclockwise). 4) if W = 4.0 rad/s and a = 6.3 rad/s2, length I = 1.5 m, and angle 0= 36°, what is the magnitude of the angular velocity of link AB? Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. 0.5 m 0, a B Your Answer: Answer units

Can anyone help me with these questions please

Problem 1 A Mechanisms Enthusiast Club is using a rigid bar (length LAB = 18 in.) with wheels riding along horizontal and sloped (angle = 45°) surfaces to demonstrate rigid body acceleration. Point B is measured with video analysis software at the instant shown (ß = 30°) to be traveling at VB = 20 in/s to the right while slowing down at ag = 5 in/s². A Using vector math, determine the velocity and acceleration of point A. Ө B G LAB ав B VB
