WebHence force = Ma, force = -A4Mπ^2/T^2. And k = Force divide by displacement, giving k = maximum force divide by the simultaneous maximum displacement, which gives k = (-A4Mπ^2/T^2)/A. 6. So the A cancels out, giving k = -4Mπ^2/T^2. This negative sign means the direction of force is inwards, which can be neglected. k = 4Mπ^2/T^2 WebThe kinetic energy of the spring is equal to its elastic potential energy, i.e. 1/2mv^2 = 1/2kx^2 when the spring is stretched some distance x from the equilibrium point and when its mass also has some velocity, v, with which it is moving. This occurs somewhere in between the equilibrium point and the extreme point (extreme point is when x ...
