General Planar Motion - Example Problem 6.8-2
A uniform slender bar (L = 1.5 m) rests on a smooth horizontal sheet of ice when a force F is applied normal to the bar's longitudinal axis at point P. Point P is observed to have an initial acceleration aP of 10 m/s2, and the bar has a corresponding angular acceleration α = 9 rad/s2, in the directions shown. Determine the distance d.
Given:
- L = 1.5 m
- α = 9 rad/s2
- aP = 10 m/s2
Find: d
