How do you relate and explain a planet's distance from the Sun to things like the time of their year & their average tempareature
I am in summer school for physics and I got this question for home work. A rock climber of mass 55 kg is hanging suspended from a rope tied to another climber of mass 65 kg on a horizontal cliff ledge. If the coefficient of kinetic friction between the climber on the ledge and the ledge 0.45, what is the net acceleration of the climber on the ledge? I have been stuck on this question for 2 hours and I need it for tomorrow can anyone help me. Thanks
