Answer:
i dont get how this is a math question
and can you post a screenshot so i can understand it better
Step-by-step explanation:
<span>A projectile is fired with an initial velocity of 450 ft / sec and with an elevation angle of 30 ° above the horizontal, calculate
a) its position and speed after 8s,
The position after 8 seconds will be as follows
horizontal distance:
x=V</span>×t
x=450×8
=3600 ft
b) the maximum height reached will be given by:
H=[v² sin²θ]/2g
Plugging in the values we get:
H=[450²×sin²30]/(2×10)
H=2,531.25 ft
20.0 because it was 20.4 but round it and you get 20.0
You just need to plug in 1, 2, 3, and 4.
10*4(1)-1=39
10*4(2)-1=79
10*4(3)-1=119
10*4(4)-1=159
