A student measures the force required to stretch a spring by various amounts and makes the graph shown in Figure, which plots this force as a function of the distance the spring has stretched. (a) Does this spring obey Hooke’s law? How do you know? (b) What is the force constant of the spring, in N/m? (c) What force would be needed to stretch the spring a distance of 17 cm from its unstretched length, assuming that it continues to...
A spring whose spring constant is 947.7 N/m has been stretched by a force of 5.5 N in the +x direction. Its full stretched length is measured to be 10.6 cm. What is the original, unstretched length of this spring?

A massless spring is lying on a frictionless horizontal table. It has a spring constant of 800 N/m with an unstretched length of 23 cm and a 3 kg block is attached to its free end. You stretch the spring to a length of 33 cm and release it from rest. a) How fast is the block moving when the length of the spring is 28 cm? (Use ? = ?2 − ?1.)
It takes 6.5 J of work to stretch a spring 4.1 cm from its unstressed (relaxed) length. a) How much (in J) spring potential energy is then stored by the spring? b) What is the spring constant k in N/m? c) What if the spring is compressed instead by 4.1 cm from its unstressed length, how much (in J) spring potential energy is then stored by the spring? d) How much work (in J) is needed to compress the spring...
