Answer:
Step-by-step explanation:
Givens
r = 50
Formula
V = 4/3 pi r^3
Solution
V = 4/3 * 3.14 * 50^3
V = 4.19 * 50^3
V = 4.19 * 125000
V = 523750
1) 270 Fahrenheit
2) 34 Minutes
3) 48 Seconds
Answer:
1436.76
Step-by-step explanation:
V=4
3πr3=4
3·π·73≈1436.75504
If the plane is starting from rest, then the acceleration <em>a</em> that it needs in order to speed up to 324 km/h = 90.0 m/s over a distance of 1.35 km = 1350 m satisfies
(90.0 m/s)² = 2<em>a</em> (1350 m) ==> <em>a</em> = 3.00 m/s²
(use the kinematic equation, <em>v</em> ² - <em>v₀</em>² = 2<em>a</em> ∆<em>x</em>)
and the amount of time <em>t</em> needed to reach this speed is such that
90.0 m/s = (3.00 m/s²) <em>t</em> ==> <em>t</em> = 30.0 s
(<em>v</em> = <em>v₀</em> + <em>at </em>)
