A toddler drops his pacifier from the Royal Gorge Bridge in Colorado. If the pacifier took 7.71 s to fall how fast was it traveling when it hit the water?

75.56 m/s

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s

Time (t) = 7.71 s

Acceleration due to gravity (g) = 9.8 m/s²

Final velocity (v) =..?

Thus, we can obtain the velocity (v) with which the pacifier hit the water as follow:

v = u + gt

v = 0 + (9.8 × 7.71)

v = 0 + 75.558

v = 75.558 ≈ 75.56 m/s

Therefore, velocity with which the pacifier hit the water is 75.56 m/s

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
