In Sample Problem 9-7 the coefficient of static friction between the ladder and the ground is 0.54. How far up the lad- der can the firefighter go before the ladder starts to slip?

It is important to note that the positive value of x highlight the fact that measurements to the left of point O has been to be as positive as a part of convention for this question.
Therefore, the ladder will not slip as long as the horizontal distance of the firefighter from point O is 6.6 m .
