Quisiera ayudarte pero no puedo apenas voy a pasar a secundaria :(
1.could be anything... make sure there is safety nets below in case of an accident?
2. F1 car is more stable because the center of gravity is lower than the double deckers center of gravity
3. To find the mass of an object just put it on the scale, to find the volume put the object in a marked beaker to measure the water displacement which is the volume
Answer:
You know that force and acceleration are connected through mass, or:
F
=
m
a
Here you have:
10
=
5
m
so that
m
=
10
5
=
2
k
g
;
Then if you have
a
=
8
m
s
2
you get:
F
=
2
⋅
8
=
16

Because in reality there are frictional forces acting on the ball, against the direction of its motion. In fact, because of the friction between the ball and the surface, the ball loses little by little its energy, so its velocity decreases and eventually it stops.
In an ideal world with no friction, there would be no forces acting on the ball, so its energy must be conserved and this means that the ball would continue its motion forever.
