A box of mass 96 kg is pushed up an inclined plane which makes an angle of 21 degrees with the horizontal. The box moves at a steady speed of 3.2 m/s.
(a) What force, parallel to the plane, is being applied? (4 marks)
(b) What horizontal force is require to produce the same results? (2 marks)
I can't name any off the top of my head.
The Attempt at a Solution
I'm having some trouble understanding mostly Part A of this question. What does it mean by parallel to the plane? Is it like the force of friction or gravity?
