Answer:
the last one
Step-by-step explanation:
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
6 hours: 1 book
A unit rate is expressed as a quantity of one and shows how much is achieved in 1. In this case you get 6 hours from 1 book.
Hope this helps
