Amass m is attached to a large spring with spring constant 5 g/m, causing it to stretch from its equilibrium position by 39.2 m (a) determine the value of m (b) find the value of the damping coefficient y which would result in the spring being critically damped. 5et (c) suppose that the mass is driven by a decaying exponential force of the form g(t) assuming that the damping coefficient is given by the value of y described in part (b), indicate the second-order equation which models this situation, and solve it using appropriate non-homogeneous technique an (d) now suppose that the mass is driven instead by a decaying exponential force of the form 5e again assuming that the damping coefficient is given by the value of y g(t) described in part (b), indicate the second-order equation which models this situation, and solve it using an = appropriate non-homogeneous technique
