QUESTION 5 Consider a mass-spring system described by + b dx -+ 4x =0 with initial condition x(0) = -1 and x'(0) = 1. a) Determine the value of b so that the motion is critically damped. (2 marks) b) Suppose the equation of motion of the spring-mass system is x(t) = e-2t(3t - 1). Determine the time at which the mass passes through the equilibrium position. (2 marks) c) Find the equation of motion if force of sin2t is exerted on the system. (4 marks)
