You are climbing on a hill that is inclined at 15° with the horizontal and you wish to build a rope tow to pull yourself up. Ignoring friction, calculate the tension you needed on the rope to give your body that has a mass of 45kg at 1.5 m/s^2 acceleration. What if you are to consider the friction of 100N, what is the value of the tension and coefficient of friction?
