It will move in the direction you pushed it, but it will go at a certain velocity
Answer:
by doing the test over and over again until you get the right results
Explanation:
Answer:
The answer is 3.33m
Explanation:
The acceleration "a" is constant.
Acceleration is the variation of velocity over time,
.
solving the last equation
,
where
because the airplane starts from rest.
Once again, velocity is the variation of distance over time.

then

where
if we consider the end of the runway as the initial point (this step is for simplicity but you can let it expressed, it's going to cancel anyway).
If
at
, then

and the final expression for the distance is
.
If t = 2s, x = 4.44 m. Which means thad the additional distance is

The density of an object is given by:
D = M/V
D = density, M = mass, V = volume
The volume of the cube V is given by:
V = s³
where s = side length
Make a substitution:
D = M/s³
Given values:
M = 20kg, s = 20×10⁻²m
Plug in and solve for D:
D = 20/(20×10⁻²)³
D = 2500kg/m³
