Problem

A non-ideal spring has the following force–extension behaviour: from

x = 0

0.05\,\text{m}

, the force increases uniformly from

0\,\text{N}

10\,\text{N}

; from

x = 0.05\,\text{m}

0.10\,\text{m}

, the force remains constant at

10\,\text{N}

. Find the total work done in stretching the spring from

x = 0

0.10\,\text{m}

. a)

1.00\,\text{J}

0.25\,\text{J}

0.75\,\text{J}

0.50\,\text{J}
