The special olympics raise 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 thus a constant acceleration, and moves the plane 3.7 m in 6.1 s (an excellent time),

a. what force does the team pull with?
b. what is the speed of the plane at the end of the pull?
c. what fraction of the team’s work goes to kinetic energy of the plane?
