    Describe two different ways to determine the force constant of a rubber band only a 100g mass, a stopwatch, and a meter stick.

    I don't really understand what its asking but I dont have many formulas to choose from so I don't really know where to begin. I have like f = 1/T y = A * cos (2pi/T * delta T) etc... T = 2pi * sqrt(m/k) and F = -kx. Is it referring to the force constant or SPRING constant? Can someone give me a hint? It should be very easy but I'm having a really hard time here :cry:

    I think that the 'force constant' is refering to the 'spring constant'. If this is the case you can use two of your formula's above.
