Question

A 100-kg fisherman and a 500-kg supply crate are on a frozen pondthat is essentially frictionless. The man and the crate areinitially separated by a distance of 600 meters. The fisherman usesa very light rope to pull the crate closer to him. How far has theman moved when the crate reaches the fisherman?
A) zerometers
B) 50 m
C) 10 m
D) 100 m E) 500 m A 100-kg fisherman and a 500-kg supply crate are on a frozen pondthat is essentially frictionless. The man and the crate areinitially separated by a distance of 600 meters.

B) 50 m
C) 10 m
D) 100 m E) 500 m

Explanation / Answer

the centre of mass of the system is stationary therefore, the distance by which the men moved: d=600*(500)/(500+100)=500 m => answerE
