The Special Olympics raises money through "plane pull" events in which teams of 28 people compete to see who can pull a 75,000 kg airplane 3.5 m across the tarmac. The inertia of the plane is an issue, but so is the 13,500 N rolling friction force that works against the teams. If a team pulls with a constant force and moves the plane 3.5 m in 6.3 s (an excellent time), what fraction of the team's work goes to kinetic energy and what fraction goes to thermal energy?

a) 3/4 kinetic, 1/4 thermal
b) 1/2 kinetic, 1/2 thermal
c) 1/4 kinetic, 3/4 thermal
d) 2/3 kinetic, 1/3 thermal
