As you said it was dropped so in that case I'll take 78.4 meters as the height..
we know that
h = ut + 0.5*g*t(sqr)
t(sqr) = 78.4/(0.5*9.8) [g = 9.8 ms-2]
t = √16
t = 4
So it'd take 4 seconds
<u>Answer</u>:
B) The perimeter of the rectangle is 28 units.
E) The coordinates for the fourth vertex of the rectangle are (−5, −3).
<u>Step-by-step explanation</u>:
The length of the rectangle is 9 and width is 5.
- The perimeter is 2( 9 + 5 ) = 28 units
<em>as the upper one is right. Option A eliminated. </em>
- The coordinates for the fourth vertex of the rectangle are (−5, −3).
<em>as the upper one is right. option C and D will be eliminated.</em>
