The position where the package strikes the ground is 136.3m.
<h3>
Time of motion of the package</h3>
Use the following kinematic equation;
h = vt + ¹/₂gt²
179 = 47t + ¹/₂(9.8)t²
179 = 47t + 4.9t²
4.9t² + 47t - 179 = 0
solve the quadratic equation using formula method;
a = 4.9, b = 47, c = -179
t = 2.9 seconds
<h3>Horizontal distance traveled by the package</h3>
X = vt
X = 47m/s x 2.9 s
X = 136.3 m
Thus, the position where the package strikes the ground is 136.3m.

Answer:
The correct answer is "3899.92 N".
Explanation:
The given values are:
Force,
Ratio,
As we know,
Area, 
or,
⇒ 
On substituting the value of "A", we get
⇒ 
⇒ 
On applying cross-multiplication, we get
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
⇒ 
Here I =0.4 amp and t=2hr or 2×60×60 sec
We known I=nQ/t where Q is charge and n is no of charge.
n=It/Q
0.4x(2x60x60)/1.6x10^-19
I believe it's the the third one. :)
