Question

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?

Answer 1

75.56 m/s

Step-by-step 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
