The force of the wind over an area increases as the square of the wind velocity. o true o false

True

Explanation:

The wind will exert a force on a body no matter the size of the object

The force on an object due to wind is given by

The unit is Newton

Where,

= Density of air

A = Surface area of object

v = Velocity of air

Hence, it is true that the force of the wind over an area increases as the square of the wind velocity.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
