APFIVE Torque and Angular Acceleration of a Rod
A uniform rod of mass M and length L is pivoted at one end and released from rest in a horizontal position. If a force F is applied perpendicular to the rod at its midpoint during the fall, what is the angular acceleration of the rod?
A
α = 3F/(2ML)
B
α = F/(ML) + 3g/(2L)
C
α = 2F/(ML) + 3g/(2L)
D
α = 3F/(2ML) + 3g/(2L)
