Answer:
The mass is 16 [g]
Explanation:
We have to remember the formula that defines density, which mentions that the density is equal to mass divided by the volume.
![Density = mass / volume\\where:\\density = 2[\frac{g}{cm^{3} } ]\\Volume = 8 [cm^{3}]](https://tex.z-dn.net/?f=Density%20%3D%20mass%20%2F%20volume%5C%5Cwhere%3A%5C%5Cdensity%20%3D%202%5B%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D%20%5D%5C%5CVolume%20%3D%208%20%5Bcm%5E%7B3%7D%5D)
Now we clear the mass:
![mass= density*volume\\mass = 2[\frac{g}{cm^{3} }]*8[cm^{3} ]\\mass = 16 [g]](https://tex.z-dn.net/?f=mass%3D%20density%2Avolume%5C%5Cmass%20%3D%202%5B%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D%5D%2A8%5Bcm%5E%7B3%7D%20%5D%5C%5Cmass%20%3D%2016%20%5Bg%5D)

Answer:
a) a = 1,865 m / s² and b) t = 8.1 s
Explanation:
a) Let's use Newton's second law to find acceleration, we can work the equation in scalar form because displacement and force have the same direction
F = m .a
a = F / m
a = 8.02 10² /4.3 10²
a = 1,865 m / s²
b) We use kinematic relationships in one dimension
vf = vo + at
vf = 0 + a t
t = vf / a
t = 15.1 / 1.865
t = 8.1 s
