A rope connect two masses, M₁ = 8 kg., and M₂ = 5 kg. They are initially held at the same height above the ground, h₁ = 1.5 m, with the left (larger) mass connected by a spring to the ground. When the masses are released, M₁ goes down .25 m, and M₂ goes up .25 m. The spring is initially uncompressed. Both masses are initially and finally at rest. The objective of this problem is to find the value of k for this spring using conservation of energy. h₁ M₁ 1.5m M₁: PEgi . What are the values of the initial potential energies of each mass and the spring? Get numbers for each of these. M₂: PEgi Spring PEsp = PE₁ = KE, E₁ M₂ b. What are the TOTAL PE₁, KE₁, and E₁? Get numbers for each of these. Joules Joules Joules Joules Joules Joules M₁ h₁ = 1.25 m M₂ h₂f = 1.75 m

Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The potential energy is the measure of the net work done by or on the body. The spring potential energy is the potential energy stored due to the deformation of an elastic spring and this elasticity is due to the stretched spring. The elasticity is the ability of a solid-state matter to come back to its equilibrium position or original position after any kind of external force is acted on it. It is also known as Elastic potential energy. The potential energy here is caused due to the displacement of the spring from its equilibrium position to another position and this potential energy is equal to the net work done due to the stretching of the spring. It also resembles the same mechanics of the oscillation of a simple pendulum, where due to the external force, the object moves from its equilibrium position to its maximum ends and the periodic motion continues till it comes back to the equilibrium position to rest.
