What does the simile mean between a roller coaster can feel like flying
Nostrana [21]

Answer:

Knowing that a simile is a comparison between two things/ideas using the words "like" or "as"--->

A roller coaster can feel like flying because similar to how you would imagine flying to feel like (almost free-falling, liberated, vulnerable, yet invigorating, etc.), a roller coaster enables you to feel the same way, you are high up in the air racing at fast speeds and looping in some way that somehow defies the laws of physics ✨ yes fun stuff

Essentially, roller coasters can feel like flying because flying and roller coasters give the same feelings of excitement and also being high up in the air, since being on the ground won't take ya anywhere.

A ball is thrown into the air at a velocity of 44 feet per second. Its height in feet, h after t seconds is represented by the e
Lady_Fox [76]

Answer:

0.447 sec

Explanation:

velocity = distance/ time

distance 'h' is a function of time 't' given by

h = 12t^{2} + 44t + 16

⇒ differentiating equation

⇒ velocity = \frac{dh}{dt} = 24t + 44

⇒ acceleration = \frac{d^{2}h }{dt^{2} } = 24 \frac{ft}{sec^{2} }

deceleration due to gravity = -9.8 m/sec^{2} =  - 9.8 x 3.281 = - 32.154 ft/ sec^{2}

Net deceleration = 24 - 32.154 = - 8.15 ft/ sec^{2}

at maximum height v = 0

v^{2} = u^{2} + 2ah

⇒  0 = 44^{2} + 2 (-8.15)h

⇒ h = 118.72 ft⇒

118.72 = 12t^{2} + 44t + 16

⇒ 12t^{2} +44t - 102.72 = 0

⇒  t = -44 ± \sqrt{44^{2} - 4(12)(102.72) }     / (2 x 12)

t = 0.447 sec
