Does that mean I use the same formula? You lost me.hutchphd said:The spring energy goes to Kinetic Energy .
No, I could really use some help. I've been doing this problem for the past hour.Steve4Physics said:The question tells you the motion is horizontal. So what happens to the gravitational potential energy?
Do you you know the formula for kinetic energy?
Kinetic energy is ##\frac{1}{2}mv^2##jamesgunn said:No, I could really use some help. I've been doing this problem for the past hour.
Ok, I do know that actually. How do I apply this to get the speed for the ball though?Steve4Physics said:Kine

It's one of the most important formulae in basic physics!
Q1.What is the energy stored in the spring when its compression = 4cm?jamesgunn said:Ok, I do know that actually. How do I apply this to get the speed for the ball though?
A spring constant, also known as the force constant, is a measure of the stiffness of a spring. It represents the amount of force required to stretch or compress a spring by a certain distance.
Hooke's Law states that the force exerted by a spring is directly proportional to the distance it is stretched or compressed. The constant of proportionality is the spring constant, which is represented by the letter k.
The spring constant can be calculated by dividing the force applied to the spring by the distance it is stretched or compressed. This can be represented by the equation k = F/x, where k is the spring constant, F is the applied force, and x is the distance.
The units of spring constant depend on the units used for force and distance. In the SI system, the units of spring constant are N/m (newtons per meter). In the English system, the units are lb/in (pounds per inch).
The spring constant determines how much force is needed to stretch or compress a spring by a certain distance. A higher spring constant means the spring is stiffer and requires more force to stretch or compress, while a lower spring constant means the spring is more flexible and requires less force. This affects the spring's ability to store and release energy, as well as its resonance frequency.
