(a)[4]
Describe an experiment used to find the spring constant of a spring. State: the apparatus you would use; how the measurements should be taken; how the spring constant is calculated. You may use the space below to add a labelled diagram in your answer.
(b(i))[1]
Two springs Q and R are being tested to find their spring constants. Each spring is tested until its limit of proportionality. Define ‘limit of proportionality’.
(b(ii))[1]
Calculate the extension of each spring for this weight.
(b(iii))[1]
State and explain which spring would be the better choice for the baby bouncer shown in Fig. 2.1.
