4. When a flexible bag filled with sand is dropped on the pan of a spring balance from a height of h = 4 cm above the pan, pointer of the balance suddenly shoots to a reading m1 = 6.0 kg and after several oscillations finally settles to a reading m2 = 2.0 kg. If force constant of the spring is k = 1.5 kN/m and dry friction is absent, find mass of the pan. Assume acceleration of free fall g = 10 m/s?. Ans: 2kmž h My=2Kq Pseudo
