Question

A mountain climber (m1= 75kg) hangs vertically from a cliff, tied to her friend standing on an inclined plane at 22° degrees above the horizontal. If the force of friction between the rope and the plane is 72 N,

What minimum mass of her friend will stop her from falling?

If the friend’s mass is 86 kg, calculate the acceleration of both climbers.

Answer 1

m1*g-72-massfriend*g*sin22=0 If I am viewing it in my mind correctly., and assuming no friction holding the friend.
