Answer:
The woman's distance from the right end is 1.6m = (8-6.4)m.
The principles of moments about a point or axis running through a point and summation of forces have been used to calculate the required variable.
Principle of moments: the sun of clockwise moments must be equal to the sun of anticlockwise moments.
Also the sun of upward forces must be equal to the sun of downward forces.
Theses are the conditions for static equilibrium.

Answer:
impulse acting on it
Explanation:
The impulse is defined as the product between the force applied to an object (F) and the time interval during which the force is applied ():
We can prove that this is equal to the change in momentum of the object. In fact, change in momentum is given by:
where m is the mass and is the change in velocity. Multiplying and dividing by
, we get
and since is equal to the acceleration, a, we have
And since the product (ma) is equal to the force, we have
which corresponds to the impulse.
