A cart of mass 0.68 kg is attached to one end of of a spring and placed on a low-friction track, inclined at an angle of 61.5 degrees with respect to the horizontal. The cart is found to be in equilibrium when the spring is stretched to a total length of 52.0 cm. Given that the rest length for the spring is 12 cm, what is the spring constant for the spring
