Standing on a frictionless surface (like a sheet of ice), two boys, one strong and one weak, are attempting to break a string in half by pulling on its opposite ends. If the only horizontal forces they exert are on the string, who is exerting more force?

Explanation:

The strongest boy will exert a higher force compared to the weak one. There will be a net force created as a result of the interaction of the two forces which will cause the strong and weak boy to move towards each other because of the friction-less surface but the weak one will have a greater acceleration compared to weak one.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
