a body of mass 1 kg fall freely from a height of hundred metre on a platform of mass 3kg which is mountain on spring having a spring constant K barabar 1.25 into 10 to the power 6 Newton per metre the body St to the platform and the springs maximum compression is found to be x then value of x will be close to |

Answer» Acc. TO me, I think your answer is 4 cm ---------------------------------------------- Use conservation of energy Energy released =energy absorbed by spring when fall from H height when ball fall height h so body do work work done by gravitat. POTENTIAL Energy=work done to compress spring 1/2*K*x^2=mgh 1/2*1.25*10^6*x^2=1*10*100 If you solve then x^2=1/625 x=1/25 x=0.04m x=4cm I hope you understand my answer
