Question

How FAR will a book fall in 4.5 s if it's dropped from rest? *
Remember that d = 1/2 at^2, and here a is the acceleration due to gravity (10 m/s^2)

Answer 1

Answer:

Given

initial velocity (u) =0

time (t) = 4.5s

acceleration (g) = 10m/s^2

$we \: know \: that \\ d = ut + \frac{1}{2} a {t}^{2} \\ d = \frac{1}{2} (10) {(4.5)}^{2} \\ d = 101.25m$
