suppose you were on the moon instead of on the earth. Assuming your average reaction time is the same, how far would the yardstick fall? Gravitational acceleration on the moon is 1.67m/s2.
The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Determine the angular accelerations of CB and AB at this instant.
