maximum extension is achieved with a load of 2N, so
x/2 = 0.6/0.5
x = 2.4
so, 2N will extend the cord to a length of 37.4 cm, and then it will either snap or stop stretching.
An elastic cord can be stretched to it's elastic limit by a load of 2N.if a 35 cm length of the cord is extended 0.6 cm by a force of 0.5 N, what will be the length of the cord when the stretching force is 2.5 N
