Answer:
use the kinematics equations and solve for time, after that use dleta dx=Vi*delta time
Answer: 1.8m
Explanation:
Using the principle of moment to solve the question which states that the sum of clockwise moment is equal to the sum of anticlockwise moments.
The boy moves in the clockwise direction towards the pivot while the girl moves in the anticlockwise direction towards the pivot.
Since moment = force × perpendicular distance
CW moments = 60×1.5 = 90Nm
ACW moments = 50×x = 50x
Equating both moments to get 'x'
90 = 50x
x =9/5
x = 1.8m
This shows that the girl must sit 1.8m from the other side for equilibrium.:
That's false..
It's actually the other way around.
The believe that the best answer among the choices provided by the question is a small nucleus with electrons moving around it
