Hope this helps/works.
This is good information, but the question part is missing. Put the question in the comments and I'll try my best to help!
To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
Answer:
~ 2.3%
Step-by-step explanation:
A percentage is a amount divided by the total.
2/85 (2 is the amount decreased) 0.02352941176470588235294117647059
That makes around 0.023.
That multiplied by 100 is 2.3 and that makes the percentage.
So yeah.
