Q. A 15m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes 60 angles with the horizontal.

1) find the horizontal and vertical forces that ground exert on the base of the ladder when an 800N firefighter is 4.00m from the bottom

2) if the ladder is just on the verge of slipping when the firefighter is 9.00m up, what coefficient of static friction between the ladder and the ground.
