A load is attached to a spring, as shown in Fig. 3.1. The load is pulled downward by a few centimetres and then let go. The spring and load then oscillate up and down.
(a(i))[1]
State the position of the load when the spring’s elastic (strain) energy is at its maximum.
(a(ii))[1]
State the position of the load when its kinetic energy is maximum.
(b(i))[1]
State the conservation of energy principle.
(b(ii))[3]
Describe the energy changes as the spring and load oscillate and suggest why the load and spring finally come to rest.
