Work = Force x Distance
The masses of sled and brother don't matter in the calculation. They help determine the friction force, and the division of work between kinetic energy, potential energy (if uphill) and frictional heat.
Georgie was pulling her brother (of mass
25 kg) in a 10.4 kg sled with a constant force
of 24 N for one block (72 m).
How much work did Georgie do?
Answer in units of J.
