Answer:
Step-by-step explanation:
To find the difference between the distance of each swing, we need to subtract vectors and find the module of the resulting vector.
[tex]d_{1}=(55,5)[/tex] represents the first swing.
[tex]d_{2}=(75,10)[/tex] represents the second swing.
In the image attached, the difference is shown by vector [tex]w[/tex].
Mathematically, this displacement is defined
[tex]w=d_{2}-d_{1}[/tex]
[tex]w=(75,10)-(55,5)\\w=(75-55,10-5)\\w=(20,5)[/tex]
Now, we find its module
[tex]|w|=\sqrt{20^{2} +5^{2} }=\sqrt{400+25}=\sqrt{425}\\ |w| \approx 20.6[/tex]
Therefore, the distance difference between those swings is 20.6, approximately.
Answer:
20.6 is the difference from the first to second hit
