Question

Can you predict the force needed to stretch the rubber band to 40.0cm?why or why not

Answer 1

not much info...

Answer 2

Yes, we can using F_T = (const.)T(L/L_0 - L-0^2/L^2). The constant is depending on the material, in this case, the rubber band. T = temperature. However, there should be information about initial length (L_0).
