A meterstick pivoted about a horizontal axis through the 0 cm end is held in a horizontal position and let go. (a) What is the tangential acceleration of the 100 cm position? (b) Which position has a tangential acceleration equal to the acceleration due to gravity?© BrainMass Inc. brainmass.com April 3, 2020, 2:31 pm ad1c9bdddf
a) Fg acts on center of meterstick. Therefore, torque T:
T = mg(0.5m)
angular acceleration a ...
This solution is provided in 93 words. It uses brief calculations for torque and angular acceleration to find the tangential acceleration.
