Answer 1

E; Ef using conserwation of energy (51 + Pe); = (kE+PE}+ Initially both at rest ,so kei=OJ PEi= K9,92 r As both masses are iden identical, so final veloity is same = v finally energy tf = KE APE = phyta K9192 muz + + -mve to muz Ei= Ef K9.9 my2 -) V- Veronika q ME 9x109 V- x 8.54106 m/s = 2082.066 m/s 34106 x 5x102 = 2.1X103 m/s
