Please solve and draw diagrams for better understanding

A 2,347 g mass is hung on a "massless" vertical spring with a spring constant of k = 330 N/m. The mass is pulled down and released such that it undergoes simple harmonic motion with an amplitude of 10.0 cm. a) What is the spring potential energy of the system in Joules when the mass is located 6.7 cm below the equilibrium position (about which the mass oscillates)? Enter an answer with one decimal place in the box below. The mass in part a) is now removed and a new 391 g mass is hung from the same spring (k = 330 N/m). This new mass is pulled down 3.24 cm below the equilibrium position and released. It starts undergoing simple harmonic motion. b) Find the velocity of the mass in m/s at t = 5.5 s. If the mass is moving upwards the velocity should be positive and if it is moving downwards the velocity should be negative. Enter your answer for b) with two decimal places in the box below
