The maximum vertical distance should be calculated through the equation,
                                d = (Vf² - Vi²) / 2a
Where Vf is the final veloity, Vi is the initial velocity and a is the acceleration due to gravity (32.1740 ft/s²). Substituting the known values,
                               d = (0 - 52²) / 2(-32.1740 ft/s²) 
                                     d = 42.02 ft
The time it will take for ball to travel this distance is calculated through the equation,
                                   d = (Vo)(t) - 0.5gt²
Substituting the known values.
                                    d = (52)(t) - 0.5*32.1740t²
The value of time is 1.60 s. Thus, the nearest answer to this item is answer B.

Find radius from this sentence plz
Citrus2011 [14]

Answer:

1.2 inches

Step-by-step explanation:

Area of sphere

A = 4πr²

17.6 = 4(3.14)r²

17.6 = 12.56r²

Divide both sides by 12.56

1.4012738854 = r²

Take the sqaure root of both sides

1.1837541491 = r

Rounded

r = 1.2
