A large spool of wire cable comes off a truck and rolls down theroad which has a grade of 30 degrees with level. The outer diameterof the spool is one meter, and the diameter of the wound wire ishalf a meter. Assume the mass of the spool is negligible comparedto the mass of the wire. A half meter diameter barrel packed solidfalls two seconds later and rolls behind. Will the rolling barrelcatch up with the rolling spool before they run into something?
