A Bulldozer Attempts to Drag a Log Weighing 500 N

Short Answer

A bulldozer attempts to drag a log weighing 500 N along the rough horizontal ground.
The cable attached to the log makes an angle of 30° above the ground. The coefficient of
static friction between the log and the ground is 0.50, and the coefficient of kinetic friction
is 0.35. What minimum tension is required in the cable in order for the log to begin to
slide?
