Georgie was pulling her brother (of mass
26 kg) in a 11.9 kg sled with a constant force of 37 N for one block (100 m). How much work did Georgie do? How long would a 300 W lightbulb have to glow to produce the same amount of energy
expended by Georgie?

Work = Fd = 37 * 100 = 3700 Joules.
300 W. = 300 Joules/s.
3700/t = 300,
Solve for t.
300 W. = 300 Joules/s.
3700/t = 300,
Solve for t.
