## Question:

An S3 robot took 11.2 s to lift a 0.805 kg object 0.188 m. The voltage across the battery of the robot is about 3.80 V, and while the robot was lifting the object, the current through the battery was about 1.71 A. What was the resulting change in thermal energy? Assume the system is isolated and g = 9.81 N/kg.
