A 2.50-kg block on a horizontal floor is pushed against a horizontal spring that is initially compressed 0.0300 m. The spring has force constant 900 N/m. The coefficient of kinetic friction between the floor and the block is ??=0.30. The block and springare released from rest, and the block slides along the floor. a.What is the speed of the block when it has moved a distance of 0.0200m from its initial position? (At this point the spring is compressed 0.01 m.) b.What distance does the block travel from its initial position to where the block finally stops? (The block leaves the spring when the spring is unstretched or uncompressed)

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.
