When you hang a 100 g mass from a spring, the spring stretches 2 cm. If you remove the 100 g mass and hang another object of unknown mass, the spring stretches 6 cm. What is the mass of the object? (Assume the spring obeys Hooke’s law and doesn’t stretches beyond its elastic limit). What is the value of the force constant k of the spring in the above problem? HINT: Remember that the force of gravity on a mass (the weight) is given by F = m g, where g = 10 m/s2. Also remember that 1 N = 1 kg m/s2.
