Jake drops a book out of a window from a height of 10 meters. at what velocity does the book hit the ground? answer choices: a: 7.0meters/second b: 10meters/second c: 14meters/second d: 28meters/second

C is your answer. we know V^2-U^2=2 as where V=final velocity.
U is inital velocity
A= acc.
s= distence
a.t.q
v^2 -o^2 =(2*9.8*1o)
so, V=14 m/s

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
