Answer:

a. H=(1/2)*a*t^2

B.h=16.09ft

C.t= 1.22s

Explanation:

Explanation: Newton's equation of motion. This is called motion under free fall.

S=ut +(1/2)*a*t^2

Let S=H, and a=g

1.

H=ut +(1/2)*g*t^2

H=distance covered in ft(24ft)

u= initial velocity (ft/s)

t= time covered in seconds

g=acceleration due to gravity(ft/s^2)

a=g (32.185ft/s)

When u=0

H=(1/2)*g*t^2

2. H=(1/2)*g*t^2

g=32.185ft/s^2

t=1s

Juxtaposing the values into the equation

H= (1/2)* 32.185*(1)^2

H=16.09ft

3. When the maximum distance covered is 24ft, then using

H=(1/2)*a*t^2

24=0.5*32.165*t^2

24=16.09t^2

1.491=t^2

Find the square root of both sides

t=1.22s

It takes 1.22s to hit the ground

Most reactive non-metals in order?
kompoz [17]
Nonmetals often share or gain electrons. The nonmetals in the periodic table increases as you move to the right and decreases as you go down. This is because, the smaller the atom, the reactive it gets due to less electron attached to the orbits of the atom. The reactivity of nonmetals is arranged in decreasing order.   <span>
