The Special Olympics raises money through “plane pull” events in which teams of 25 people compete to see who can pull a 74,000 kg airplane 3.7 m across the tarmac. The inertia of the plane is an issue—but so is the 14,000 N rolling friction force that works against the teams. If a team pulls with a constant force and moves the plane 3.7 m in 6.1 s (an excellent time), what fraction of the team’s work goes to kinetic energy and what fraction goes to thermal energy?
