After putting it off for three months, you decide to finally trim the tree in your front yard. You use your 3.6-m long ladder and rest it against the tree so that it makes an angle of 50◦ from the ground. You climb four fifths of the way up the ladder and start trimming. Assume your mass is 72 kg, and the mass of the ladder is 13 kg. What is the magnitude of the friction force bewteen the bottom of the ladder and the ground? Note- you can assume there is no friction between the ladder and the tree.
