Answer:
The horizontal distance of Sosa is 276.526 ft or 84.28 meter.
Explanation:
As shown in the figure, let point O is the starting point of Sosa. She travels 361 ft at an angle 50 degree with the horizontal.
sin 50 = 
0.7660 = h / 361
h = 276.526 ft
h = 84.28 meter
The horizontal distance of Sosa is 276.526 ft or 84.28 meter.
For number one she is going to observe the contraction of the ballon
For number two she is going to observe the expansion of the ballon
The work she on the box will be 40 J. Here the displacement due to the force is height.
<h2 /><h3>What is work done?</h3>
Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
Given data;
Force,F = 80 N
height, h = 0.5 m
Work,W = ? J
Here the displacement is height;
W = F × d
W = F × h
W = 80 N × 0.5 m
W = 40 Nm
W=40 J
Hence work she on the box will be 40 J.

Please tell me if i am wrong but i think the answer is C. i use k12 too, but i fail to see what this has to do with physics.
