Explanation:
The boat will move -0.24 m and the negative sign indicates left direction.
<u>Explanation</u>:
mass of people A = 78 kg
mass of people B = 59 kg
mass of rowboat = 88 kg
Let the displacement of the boat be x
= 2.9 + x
= -2.9 + x
As net external F = 0
∑mx = 0
88 (x) + 78 (2.9 + x ) + 59 (-2.9 + x) = 0
88x + 226.2 + 78x - 171.1 + 59x = 0
225x + 55.1 = 0
x = -55.1 / 225
x = -0.24
The negative sign indicates left direction.
