A box of mass m = 25 kg slides with an initial speed v0 = 7.0m/s up a slope which forms the angle = 12° relative to the horizontal. A strong wind is blowing with fixed horizontals force Fv = 50N to the right (see figure). The coefficient of friction in motion is uk = 0.18. (a) What is the transverse force acting on the box from the slope? (b) How far, L, does the box slide up the slope before it stops? (c) What must be the minimum coefficient of friction at rest, us, for the box to slide not back down the hill?

Thank you
You are climbing on a hill that is inclined at 22° 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 55kg a 1.2m/s^2 acceleration. What if you are to consider the friction of 150N, what is the value the tension and coefficient of friction?
