(1 point) Set: f(t)- Prove or disprove that the Laplace transform F(s)-f(t) is . /18 126 542 1083 32 18 2 2. (1 point) Suppose that L{f(t)}-F(s). Check that 3. (1 point) Find the inverse Laplace transform S3-482 4. (.5 point for each) T or F: (AF(s) 5F5 (B) L-1 F(s) + 5e-,-L-i F(s) + δ(1-5)? 5. (6 points) Use the Laplace transform to solve the IVP Give a mechanical description of this IVP in terms of a spring-mass system (undamped, underdamped, critically damped or overdamped) and forces/instant impulses acting upon the system at specific times, including the directions of the forces. Specify parts of your solution y(t) generated by the initial conditions, by the instant impulse and by the constant force. Identify the limit lim y(t)
