Compute the vertical force

Reference no: EM13655726

A 15 m, 419 N uniform ladder rests against a friction less wall, making an angle of 63.6degree with the horizontal.

Compute the horizontal force exerted on the base of the ladder by Earth when an 808 N fire fighter is 4.09 m from the bottom.

Answer in units of N.

Compute the vertical force?

Answer in units of kN.

If the ladder is just on the verge of slipping when the firefighter is 8.44 m up from the bottom, find the coefficient of static friction between ground and ladder?
