Astudent moves a box of books down the hall by pulling on a rope attached to the box. the student pulls with a force of 187 n at an angle of 25.6 ◦ above the horizontal. the box has a mass of 31.5 kg, and µk between the box and the floor is 0.19. the acceleration of gravity is 9.81 m/s 2 . find the acceleration of the box. answer in units of m/s 2 . 019 (part 2 of 2) 10.0 points now the student moves the box up a ramp (with the same coefficient of friction) inclined at 14.3 ◦ with the horizontal. b) if the box starts from rest at the bottom of the ramp and is pulled at an angle of 25.6 ◦ with respect to the incline and with the same 187 n force, what is the acceleration up the ramp? answer in units of m/s 2 .
