Add both distances to find the total distance between them: 3447+86=3533 ft.
Answer:
36.75 feet below sea level
Step-by-step explanation:
Feet she descended in 25min
=0.5×25
=12.25
Therefore, the total feet she dived to
=12.25+24.25
=36.75
The question involves the concept & equations associated with projectile motion.
Given:
y₁ = 1130 ft
v₁ = +46 ft/s (note positive sign indicates upwards direction)
t = 6.0 s
g = acceleration due to gravity (assumed constant for simplicity) = -32.2 ft/s²
Of the possible equations of motion, the one we'll find useful is:
y₂ = y₁ + v₁t + 1/2gt²
We can just plug and chug to define the equation of motion:
<u><em>y = (1130 ft) + (46 ft/s)t + 1/2(-32.2 ft/s²)t²</em></u>
<em>(note: if you were to calculate y using t = 6.0 s, you'd find that y = 826.4 ft, instead of 830 ft exactly because of some rounding of g and/or the initial velocity)</em>
2. 3. 5. are correct
1. and 4. are actually interchanged
You can’t really know the y value unless you’re told that they’re both directly proportional. if so, then check out the pic
