<h3><u>Answer;</u></h3>
= 426 m
<h3><u>Explanation;</u></h3>
Time taken to reach Earth = t
s = ut + ½at²
Vertically initial velocity = u = 0
Therefore;
<em>132 = 0t + ½6.89t² </em>
<em>=132/3.445 = t² </em>
<em>
= 38.316 = t² </em>
<em>t = 6.19 s </em>
<em>
Range = horizontal distance = speed x time </em>
<em> = 68.9 x 6.19 </em>
<em> ≈ 426 m </em>
<em>
Hence the emergency kit impacts the ground 426 m from the survivor </em>

Answer:
<em>The force is W</em>
Explanation:
<u>Sum of Electrostatic Forces</u>
The electrostatic forces have magnitude and direction as all physical forces do. Two point charges repel each other if their charges have the same sign, and they attract each other if their signs are opposite.
The bottom two charges and the top charges are negative, thus all the forces are repulsive. Charge 1 exerts a force F1, charge 2 exerts a force F2. Please look at the diagram in the figure below. The sum of both forces is shown with a red line. The horizontal component of the forces cancel each other, thus the total force goes upward.
The correct vector that best represents the net force is W
