Ereny said:The Attempt at a Solution
i figured that out and its k= 61.9N/m
i figured the total energy which is .307J but i can't figure out KE and EPE
i really need help guys
The spring constant of a system can be calculated by dividing the applied force by the displacement of the spring. 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 displacement.
The unit for spring constant depends on the unit of measurement used for force and displacement. In the metric system, the unit for spring constant is Newtons per meter (N/m). In the imperial system, it is pounds-force per inch (lbf/in).
The spring constant is directly proportional to the potential energy stored in a spring. This means that as the spring constant increases, the potential energy stored in the spring also increases. The relationship can be represented by the equation U = 1/2 kx^2, where U is the potential energy, k is the spring constant, and x is the displacement.
Yes, the spring constant of a system can change depending on factors such as the material and dimensions of the spring, as well as the temperature and any external forces applied to the system. Changes in the spring constant can also occur due to wear and tear over time.
To determine the force exerted by a spring, you can use the equation F = kx, where F is the force, k is the spring constant, and x is the displacement. Simply plug in the values for the spring constant and displacement to calculate the force. Keep in mind that the force will be in the opposite direction of the displacement.
