Answer:
combined velocity of the system = 0.033 m/s.
Step-by-step explanation:
taking the bullet and block as single system since there is no external force involved momentum is conserved .
initial momentum of the bullet = mv
where m is the mass of bullet and v is velocity of bullet.
and initial momentum of block = 0 since its velocity is 0.
therefore initial momentum of the system = mv
= 0.005×40
= 0.2
when the bullet stick of together with the block let the combined velocity of the system be V
therefore applying conservation of momentum
mv = (M+m)V
0.2=(6+0.005)V
therefore V = 0.033 m/s
<span>I think no, now all lines of symmetry are diagonals because
it can also be horizontal and vertical.
Symmetry is also known as proportion; anything that is equal or proportion with
each other.
Let’s have an example:
A square
=> in getting the symmetry of a square, we need to draw a 2 diagonal lines
to each edges.
=> we can also draw 2 perpendicular lines that bisect to the edges of the
square and it also provide an equal parts or proportional parts.
