A student moves a box of books down the hall by pulling on a rope attached to the box. The student pulls with a force of 172 N at an angle of 21.3 above the horizontal. The box has a mass of 25.2 kg, and u between the box and the floor is 0.2. The acceleration of gravity is 9.81 m/s. Find the acceleration of the box. Answer in units of m/s. Now the student moves the box up a ramp (with the same coefficient of friction) inclined at 11.2 with the horizontal. b) If the box starts from rest at the bottom of the ramp and is pulled at an angle of 21.3 with respect to the incline and with the same 172 N force, what is the acceleration up the ramp? Answer in units of m/s. A student moves a box of books down the hall by pulling on a rope attached to the box. The student pulls with a force of 172 N at an angle of 21.3 above the horizontal.

Answer rating: 100% (QA)

To solve for the acceleration of the box we need to analyze the forces acting on it and then apply Newtons second law of motion which states that the acceleration of an object is equal to the net forc... View the full answer
