14.0 m uniform ladder weighing 490 n rests against a frictionless wall. the ladder makes a 65.0°-angle with the horizontal. (a) find the horizontal and vertical forces (in n) the ground exerts on the base of the ladder when an 850-n firefighter has climbed 4.10 m along the ladder from the bottom. horizontal

The horizontal reaction force is 230.3 N.

Explanation:

Given that,

Length l= 14.0 m

Weight of ladder F = 490 N

Angle = 65°

Weight of firefighter F'= 850 N

Height l'= 4.10 m

Suppose horizontal force magnitude N direction vertical force magnitude N direction

We need to calculate the horizontal reaction force

Horizontal reaction force = normal reaction from wall

Vertical reaction force = weight of ladder +weight of man

We need to calculate the moment about bottom is zero

Put the value in the equation

Hence, The horizontal reaction force is 230.3 N.
