Question

Two boys A and B of masses 60 kg and 40 kg are standing on a smooth ground at points P and Q of coordination (-10,0,0) & (10,0,0)m. If they move towards Each Other by pulling a common string then they will meet at
1» (-10,0,0)m
2»(0,0,0) m
3» (-2,0,0) m
4» (2,0,0)m
Ans:- (-2,0,0)

Answer 1

Answer:The answer is (-2,0,0)

Explanation:As thier is movement in a single dimension, for that particular dimension, if the point at which the meet be y then we have,

Y=(m1y1+m2y2)/(m1+m2)

= (60*(-10)+40*10)/100

= -2

Finally the point at which they will meet is (-2,0,0).

Thank you!
