PHYSICS HELP! hooks law, very easy?
a bungee cord needs to transfer 2.0×10^6J of E.
a 10 kg mass extends the bungee cord 1.3m.
what is the max extension in the bungee cord.
please i need the solution
the answer is 2.3×10^2m
thank you!
k = mg/L = 10*9.8/1.3 = 75.385 N/m
E = ½kX² → X = √(2E/k) = √(2*2E6/75.385) = 230.35 m
