QUESTION 3 a) A package of mass 20 kg is projected with an initial velocity of 8 m/s up a 15° incline as shown in Figure Q3(a). Knowing that the coefficient of kinetic friction between the package and the incline is μ = 0.12. i) Using work-energy method, determine the velocity after it has moved 3 m. (6 marks) ii) Determine the maximum distance moved up. (3 marks) iii) Using impulse-momentum method, determine the time when it stop. (4 marks) V = 0 V=8 m/s 20 kg 15⁰ Figure Q3(a) 20 kg
