A 465-g mass is attached to an ideal massless spring with a spring constant 24.5 N/m. A physics student pulls the mass and stretches the spring by 4.8 cm. At t = 0 the student lets the mass go. Find the position of the mass at t = 13 s. Neglect the friction.

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?
