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.

A box of mass 100.0kg rests on level ground and there is no friction between the box and theground. Resting on top of that mass is a 40.0kg mass with friction coecient that's unknown. A ropeis tied to the 100.0 kg mass and draped over a pulley from which a third mass hangs. How much massmust the hanging mass have in order for the acceleration of all masses to be 5ms2 ? What is the minimum possible friction coecient of the 40.0kg mass in the prior problem?

You are climbing on a hill that is inclined at 15degrees with the horizontal and you wish tobuild a rope tow to pull yourself up. Ignoring friction, calculate the tension you needed on therope to give your body that has a mass of 45kg a 1.5 m/s^2 acceleration. What if you are toconsider the friction of 100N, what is the value of the tension and coefficient of friction?
Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 92.9 kg, down a theta= 79.4º slope at constant acceleration a=-1.7 m/s2, as shown in Figure (here we assume the positive direction is going down the slope. So the given acceleration is a negative value, it means its direction is going up the slope, slowing down as it moving downward). So The coefficient of friction between the sled and the snow is 0.100. How many Joules of work is done by the tension in the rope as the sled moves 9.1 m along the hill? Use g= 10 m/s2. Your answer for this problem maybe some large number. Just put in the raw number as your answer. For example, 34567.11. But remember you have to specify if the work is positive or negative, if it is negative, you need to input, for example, -34567.11
