1. Homework Statement
A 300 gram mass is attached to a massless spring and allowed to oscillate around an equilibrium according to the equation: x(t) = 1.5*sin(12.566*t). where x is measured in meteres and t in seconds.
a.) What is the spring constant
b.) What is the total mechanical energy of the system
c.) what is the maximum kinetic energy of the mass
d.) what is the maximum velocity of the sytem
2. Homework Equations
F = -kx
Usp= (1/2)kx^2
I think the problem I am having is attempting to relate enough variables in one equation to try to solve for the spring constant, I think I understand that B and C will be the same, when Kinetic energy is at the highest potential energy will be = 0 and that will be same as the total mechanical energy, I just feel like I'm lost trying to solve for the spring constant
3. The Attempt at a Solution
I thought of trying to graph the equation of the graph given however i don't think that this is the apporpriate method to solve the problem, also i thought about substituting an arbitrary time to and try to solve for final velocity working backwards however I'm not sure how to use the equations I've learned to solve for these variables
