A mass 7kg of stretches a spring 18cm. The mass is acted on by an external force of 5sin(t/2) N and moves in a medium that imparts a viscous force of 4N when the speed of the mass is 8cm/s. If the mass is set in motion from its equilibrium position with an initial velocity of 4cm/s, determine the position of the mass at any time t. Use 9.8m/s2 as the acceleration due to gravity. Pay close attention to the units.
