Part A

What is the largest voltage the battery can have without breaking the circuit at the supports?

Part B

The batter voltage has the maximum value calculated in part (a). If the resistor suddenly gets partially short-circuited, decreasing its resistance to 2.80 W, find the initial acceleration of the bar.
