Posted by Katy on .
the wind blowing on a vertical surface varies jointly as the area of the surface and the square of the velocity. if a wind of 40 mph exerts a force of 50 pounds on a surface of 1/2 square foot , how much force will a wind of 80 mph place on a surface of 2 square feet
the equation is....
S=kwd(squared)
solve for k.

HELP PLEASE 
bobpursley,
force/50= .5*40^2/(2*80^2)
