Now use conservation of energy to calculate the value of the force constant of the spring {1:}. The Elastic PE of the spring = the Gravitational F'E of the hall II Solve this equation fork. Quantity Unit k1 {using values from trial 1] ' 159.?" Mm ' k; {using values from trial 2] F ' Hi?" Writ k3 {using values from trial 3] ' 159.?\" Mm The three values for the spring constant should be similar although not exactly the same. Hound your answers off to 1 digit after the decimal point. Make sure you give the correct units I.vith all your numbers
