H = 280 ft, the height of the flower pot.
g = 32 ft/s²
Neglect air resistance.
Note that 1 ft/s = 15/22 mi/h
The initial vertical velocity is zero.
Let v = the velocity with which the flower pot hits the ground.
Then
v² = 2gh
= 2*(32 ft/s²)*(280 ft)
= 17920 (ft/s)²
v = 133.866 ft/s
Also,
v = (133.866 ft/s)*(15/22 (mi/h)/(ft/s)) = 91.272 mi/h
Answer: 133.9 ft/s or 91.3 mi/h
Answer:
a bicycle has more kinetic energy cuz kinetic energy depends on mass and velocity.bicycle has more mass than a tennis ball.
Answer:
dimension is 20ft*20ft*10ft
Explanation:
let a,a and h are length, width and height of given tank with square base.
volume = a*a*h
surface area =aa +2(ah+ah)
for weight to minimize, surface area is to be minimum i.e.
a = 20ft
now
at a = 20 ft
h = 10ft
hence dimension is 20ft*20ft*10ft
Answer:
The air molecules in the compressions of the second wave are more dense, so the sound is louder.
Explanation:
In a closed room, Noah and Nina are sitting 15 m apart.
As Noah says the same sentence twice, Nina does not hear the sound the first time but she does hear the sentence the second time.
This happens as the air molecules in the compressions of the second wave are more dense. As a result, the sound is louder.
The correct option is ''The air molecules in the compressions of the second wave are more dense, so the sound is louder''
Answer:
I got this question on Ap3x. The answer is Car C...I got it correct
Explanation:
This is because Car C is at the lowest point with the lowest amount of potential energy. Potential energy is stored at it's highest when it has the "potential" to fall, move, or etc. Car C seems to have gone farther down from the high point of the slope, meaning that most of the potential energy transformed into kinetic energy. All in all, Car C has the least potential energy. (Please give Brainliest, or not...your choice but this is the first question that I answered)
