The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. F = ma; a = F/m. This means that Force over the mass. In order to improve the acceleration without redesigning is that the company has to improve the force assuming that the mass is still the same.
Here is your answer
Windmill- Wind energy - Mechanical energy- Electrical energy.

As wavelength increase, frequency decrease
<span>Plug in 288 for h, move it over to the right side and do the quadratic formula to solve for t. You will get 2 times, in between and including those times will give you the period it is at least 288 ft off the ground.
</span>You can simplify this and not need to use the quadratic.
<span>288=−16<span>t^2</span>+144t
</span><span>Divide through by 16 getting
18=-t^2 + 9t
</span><span><span>t^2</span>−9t+18=0</span><span> Is what you would get after rearranging the equation Now you have something you can easily factor</span><span>
