A block of mass m = 0.25 kg is connected to a spring of constant k = 0.25 N/m and a shock absorber of damping coefficient b = 0.5 N.S/m. The block is displaced from its equilibrium position to a point P to 0.1 m and released from rest. Determine:
a) Equation of displacement as a function of time;
b) What is the type of oscillation;
c) The graph of positon x as a function of time t.

A block of mass m = 0.1 kg is connected to a spring of constant k = 0.25 N/m and a shock absorber of damping coefficient b = 0.5 N.S/m. The block is displaced from its equilibrium position to a point P to 0.1 m and launched with an initial speed of 0.28 m/s. Determine:
a) Equation of displacement as a function of time;
b) What is the type of oscillation;
c) The graph of x versus t.
