A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 128.0 N at an angle of 17.0° above the horizontal. The box has a mass of 25.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (a) Find the acceleration of the box (b) The student now starts moving the box up a 10.0° incline, keeping her 128.0 N force directed at 17.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box?

If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object. Find the law describing the total force acting on this object.
