(a) Find the Laplace transform of (2t +e'} - 4cosh 2t . 4s-7 (b) Find the inverse Laplace transform of s2-s-20 A spring is stretched 10cm by a 4kg mass. The weight is pulled down an additional 20cm and released with an upward velocity of 4m/s. Neglect damping. Form an equation for the position of the spring at any time t.
