Acertain spring is found not to obey hooke’s law; it exerts a restoring force fx(x)=−αx−βx2 if it is stretched or compressed, where α=60.0n/m and β=18.0n/m2. the mass of the spring is negligible. (a) calculate the potential-energy function u(x) for this spring. let u = 0 when x = 0. (b) an object with mass 0.900 kg on a frictionless, horizontal surface is attached to this spring, pulled a distance 1.00 m to the right (the +x-direction) to stretch the spring, and released. what is the speed of the object when it is 0.50 m to the right of the x = 0 equilibrium position?

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
