Someone help Hooke's law states that the length that a spring is stretched is proportional to the applied force. A pan
hangs from a 50 cm spring. When a 10 kg mass is placed in the pan, It stretches the spring 6 cm.

5. Write a function rule l(w) that models the length of the spring based on
the mass of the object in the pan.

6. What is the mass of an object in the pan if the spring is stretched to a
length of 65 cm?
