Example 2.1 A body of mass 4 kg is supported on light springs which deflect 15.7 mm from their free length due to the weight of the body. Determine the expressions for the displacement of the mass when: (a) The mass is initially displaced downwards 100 mm from the static equilibrium position and then released from rest. (b) The body is at rest in the static equilibrium position when it is struck by an impulse of 10 Ns which acts vertically downwards.

Example 2.1
A body of mass 4 kg is supported on light springs which deflect 15.7 mm from their free length due to the
weight of the body. Determine the expressions for the displacement of the mass when:
(a) The mass is initially displaced downwards 100 mm from the static equilibrium position and then
released from rest.
(b) The body is at rest in the static equilibrium position when it is struck by an impulse of 10 Ns which acts
vertically downwards.
