Explanation 1) Concept: The bundle starts from the ground and moves up the incline. This results in conversion of its initial kinetic energy into potential energy but with some loss of energy. The energy lost is due friction with incline surface, and hence, it stops after travelling some distance up the incline. Thus, we can apply the law of conservation of energy to determine the distance travelled by the bundle up the incline. 2) Formula: i) K E = 1 2 m v 2 ii) P E = m g h iii) E t h = F f d 3) Given: i) The mass of the bundle = 4.0 kg ii) The initial kinetic energy of the bundle = 128 J iii) The angle of the incline with the horizontal = 30 0 iv) The coefficient of friction = μ k = 0.30 4) Calculations: Using the diagram of the incline, we can write, sin ⁡ 30 = h d ⇒ h = d sin ⁡ 30 and N = m g c o s 30
