Answer:
The third stage of parturition is called " after-birth".
Explanation:
"6.5 km/hr" is not a velocity. It's just a speed, so
we don't know what direction he's walking.
If he happens to be walking north, then it takes him
(12 km) / (6.5 km/hr) = 1.846... hours (rounded) .
If he's walking in any other direction, it takes him longer than that.
If the angle between north and the direction he's walking is
90 degrees or more, then he can never cover any northward
distance, no matter how long he walks.

Answer:
a = - 0.209 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
We will take the positive forces to the right and the negative forces to the left.
![155-277+113=43*a\\-9=43*a\\a = - 0.209[m/s^{2} ]](https://tex.z-dn.net/?f=155-277%2B113%3D43%2Aa%5C%5C-9%3D43%2Aa%5C%5Ca%20%3D%20-%200.209%5Bm%2Fs%5E%7B2%7D%20%5D)
The negative sign means that the box accelerates in a negative direction to the left.
