A system consists of a vertical spring with force constantk=1,250N/m, length L=1.50m, and object of mass m=5.00kg attached tothe end. The objects is placed at the level of the point ofattachment with the spring un-stretched, at position yi=L, and thenit is released so that it swings like a pendulum. (a) WriteNewton's second law symbolically for the system as the objectpasses through it's lowest point. (Note that at the lowest point,r=L-yf) (b) Write the conservation of energy equation symbolically,equating the total mechanical energies at the initial point andlowest point. (c) Find the coordinate position of the lowest point.(d) Will this pendulum's period be greater or less than the periodof a simple pendulum with the same mass m and length mass L?Explain.

If your deriving a formula can you show me how you derived becausemy teacher counts off if we don't derive the formulas. Thankyou!
