Use the position equation given below, where s represents the height of the object (in feet), v0 represents the initial velocity
iris [78.8K]

Answer:

(a) 7.5 seconds

(b) The horizontal distance the package  travel during its descent is 1737.8 ft

Step-by-step explanation:

(a) The given function for the height of the object is s = -16·t² + v₀·t + s₀

The initial height of the object s₀ = 900 feet

The initial vertical velocity of the object v₀_y = 0 m/s

The time it takes the package to strike the ground is found as follows;

0 = -16·t² + 0×t + 900

900 = 16·t²

t² = 900/16 = 62.25

t = √62.25 = 7.5 seconds

(b) Given that the horizontal velocity of the package is given as 158 miles/hour, we have

158 miles/hour = 231.7126 ft/s

The horizontal distance the package  covers in the 7.5 second of vertical flight = 231.7126 ft/s × 7.5 s = 1737.8445 feet = 1737.8 ft to one decimal place

The horizontal distance the package  travel during its descent = 1737.8 ft.

PLZ HELP ITS DUR RIGHT NOW AND PLZ ANSWER TRUTHFULLY
yuradex [85]

Answer:

x=141

Step-by-step explanation:

(n-2)•180 = Sum of all the interior angles

n = # of sides

(7-2)•180

5•180

900= Sum of all the interior angles

Add all the angles and equal them to 900

125+122+131+x+7+x+107+x-15=900

Add all the numbers up first on the left side

477+3x=900

3x=423

x=141
