Question

Your A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She puls with a force of 137.0 N at an angle of 15.0° above the horicontal. The box has a mass of 25.0 kg, and the coefficient of kinetic friction between bex and floor is 0.300. (a) Find the acceleration of the box 7.71 Your response differs from the correct answer by more than 100%, m/s2 up the ndre keeping her 137.0 N force directed at 15.0° above the line of the Incline. If the coefficient off friction is unchanged, what is the new acceleration of the box? m/s2 up the incline Need Help?
