Problem #9: (a) Given the initial value problem y' + 3y = 10 sin t, y(0) = 5, find the Laplace transform of the solution Y(s). (b) Using the Laplace transform, Y(s), find y(t), the solution to our initial value problem. *Don't forget: Your answer should be a function of t. (A) $\frac{5}{s+3} + \frac{4}{s^2+1}$ (B) $\frac{35}{s+3} + \frac{30}{s^2+1}$ (C) $5 + \frac{30}{s+3} + \frac{30}{s^2+1}$ (D) $5 + \frac{1}{s+3} - \frac{s-3}{s^2+1}$ (E) $\frac{5}{s+3} - \frac{s}{s^2+1}$ (F) $\frac{30}{s+3} + \frac{30}{s^2+1}$ (G) $\frac{1}{s+3} - \frac{s-3}{s^2+1}$ (H) $\frac{6}{s+3} - \frac{s-3}{s^2+1}$

3. In this scenario, one block is wooden, and the other one is made of ice (0.92kg/L). Both have the same volumes of 10 L each. 4.00 kg 9.19 kg a) What is the anticipated apparent weight of each block in water? b) Considering the answers from the above, describe the behavior(motion) of each block in water. Will each accelerate? c) Calculate the height to which each block is immersed in the water. Hint: start from the condition for net force. Suppose that both blocks are placed on a bottom of a 10m deep swimming pool and released. d) Which block will reach to surface of the swimming pool faster? Predict your answer e) Calculate the time and the velocity of each block when reaching the surface of the swimming pool.
