More information needed.
(a) Eu = m*g*h = 0.005*9.8*20 (b) Eu = Ek
Potential Energy = Kinetic Energy m*g*h = m/2*v^2 0.0425*9.8*27 = 0.02125*v^2 Solve for v^2. Kinetic Energy (marble) = Potential Energy (spring) m/2*v^2 = k/2*y^2 0.02125*v^2 = k/2*0.0049^2 Solve for k. Change in gravitational energy is equal to m*g*h.
