Question

A rock climber of mass 55 kg is hanging suspended from a rope tied to another climber ofmass 65 kg on a horizontal cliff ledge. If the coefficient of kinetic friction between theclimber on the ledge and the ledge is 0.45, what is the net acceleration of the climber onthe ledge?

David · Accepted Answer

Solution: 
Coefficient of kinetic friction between the climber on the ledge and the ledge (μ)= 0.45 
Mass of rock climber A = 55 kg 
Mass of climber B = 65 kg 
Friction force acting on A = μ*N (N is the normal reaction = ma*g ) 
Let the tension in the rope be T. 
Now,
