please refer to the pictures and answer the three questions

1)

A 250g (1/4 kg) mass is hung from a vertical spring with a spring constant of 98 N/m. Ify : 0 is at the bottom end of the spring when it is neutral (no mass hanging), what is the new equilibrium position when the mass is attached, in units of cm? Assume the y-axis points vertically upward. Type your numeric answer and submit J'r A 250g (1/4 kg) mass is hung from a vertical spring with a spring constant of 98 N/m. The mass is pulled down 3.0cm and released such that it begins to oscillate. What is the period of the resulting oscillations, in seconds? Assume damping can be ignored. Type your numeric answer and submit % A 250g (1/4 kg) mass is hung from a vertical spring with a spring constant of 98 N/m. Let y = 0 be at the neutral spring position (with no mass attached). The mass is pulled down 3.0cm and released such that it begins to oscillate. Match the following dynamic properties ofthe motion with the plot from the numbered set that could show the property in question if the units and scales of the axes were correct. sewage Drag and drop options on the right-hand side and submit.
