A cherry falls from a tree branch that is 9 feet above the ground.
miss Akunina [59]
The cinematic equation is:
 h (t) = (1/2) * a * t ^ 2 + vo * t + h0
 Where,
 a: acceleration
 vo: initial speed
 h0: initial height
 Substituting values:
 h (t) = (1/2) * (- 32) * t ^ 2 + (0) * t + 9
 h (t) = - 16t ^ 2 + 9
 For t = 0.2 we have:
 h (0.2) = - 16 * (0.2) ^ 2 + 9
 h (0.2) = 8.36 feet
 To touch the ground we have:
 -16t ^ 2 + 9 = 0
 16t ^ 2 = 9
 t = root (9/16)
 t = 0.75 s
 Answer:
 
The height of the cherry after 0.2 seconds is:
 
h (0.2) = 8.36 feet
 
the cherry hits the ground at:
 
t = 0.75 s

The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approxim
olga55 [171]

Answer:

7.96 *10^8kg

Step-by-step explanation:

Given

Eiffel = 9.16 * 10^6\ kg

Golden\ Gate =8.05 * 10^8kg

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

Difference = Golden\ Gate - Eiffel

Difference = 8.05 * 10^8 - 9.16 * 10^6

Express 10^8 as 10^6 * 10^2

Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6

Express 10^2 as 100

Difference = 8.05 * 100*10^6 - 9.16 * 10^6

Difference = 805 *10^6 - 9.16 * 10^6

Factorize:

Difference = (805- 9.16) * 10^6

Difference = 795.84 * 10^6

Factorize the decimal number

Difference = 7.9584 *10^2 * 10^6

Difference = 7.9584 *10^8

Approximate:

Difference = 7.96 *10^8
