Vi = 2m/s
a= 4.5 m/s
d= 340 m
vf= ?
use this equation ... vf^2=vi<span>^2+2ad
you should get vf = 55.3
hope this helps </span>

Answer:
<em>The density of the metal is</em> 
Explanation:
<u>Density</u>
The density of a substance is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:

The piece of metal has a mass of m=1200 gr. When the piece of metal is submerged in a measuring cylinder, the water level rises from 150 cm3 to 250 cm3. This means the piece of metal occupies a volume of V=250 cm3-150 cm3=100 cm3.
The density is:


The density of the metal is
