A ladder of length 10 m and mass 25 kg leans against a smooth wall such that it is at an angle of 57∘ to the horizontal.  A man of mass 70 kg stands at the point A marked in the diagram, a distance d from the foot of the ladder. The coefficient of friction between the ground and the ladder is 0.1. A)Find the magnitude of the normal reaction force N acting at the foot of the ladder.

B) What is the relationship between the magnitude of the friction F acting on the foot of the ladder, and the magnitude of the normal reaction R, acting at the top of the ladder. Write your answer as a mathematical equation (using the "=" sign) involving F and R

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
