Answer: 10.02m
Explanation: Given
M1 = 26.3kg
M2 = 52.5kg
d = 5m
If the systems centre of mass does not change, the two skaters will definitely meet at the centre of mass.
If the 26.3kg skater is a m away from the centre of the mass, then the 52.5kg skater is (5-a) m away from the centre of the mass. Thus,
M1a + M2(5-a) = 0
26.3a + 52.5(5-a) = 0
26.3 a + 262.5 - 52.5a = 0
-26.2a + 262.5 = 0
26.2a = 262.5
a = 262.5/26.2
a = 10.02m
The correct answer is - c. escape.

Explanation:
Answer: 25N
method: total force in the right hand direction is 100N and total force in the left hand direction is 125N. To get the net force, we add forces if they are in the same direction and substract if they are in opposite directions. since 100N and 125N are in opposite directions, we substract the larger value from the smaller value. Then we get 25N in the left hand direction as the final answer.
