how about the question (b).The answer you upload only until (a)......
u know the bullet is fired from the top of the building, right?
part (b) ask for the height above the ground.
h is the height
part (b) ask for the height above the ground.
h is the height
the height above the ground is the height of the building
why I can't get the answer when I use
s=1/2 (u + v ) t
(1600 +h ) = 1/2 ( 177.18+0) (18.1+1.8)
h=163 m
And the correct answer from the book is 357m.
s=1/2 (u + v ) t
(1600 +h ) = 1/2 ( 177.18+0) (18.1+1.8)
h=163 m
And the correct answer from the book is 357m.
