Answer:
Rocket Center of Gravity. As a rocket flies through the air, it both translates and rotates. The rotation occurs about a point called the center of gravity. The center of gravity is the average location of the weight of the rocket.
The body moves at a velocity of 1.62m/s after the bullet emerges.
<h3>Given:</h3>
Mass of bullet,
= 22g
= 0.022 kg
Mass of the block,
= 1.9 kg
Velocity of bullet ,
= 265 m/s

According to the law of collision which states that the momentum of the body before the collision is equal to the momentum of the body after the collision.
After penetration;


The formula for calculating the collision of a body is expressed as:
p = mv
m is the mass of the body
v is the velocity of the body
∴ Momentum before = Momentum after
Substitute the given parameters into the formula as shown:

Therefore, It moves with a velocity of 1.62 m/s.

Answer:
??? I don't get it, please explain. What is your question????
Explanation:
Explanation:
hello,
a = ( v - u ) / t
where u is the initial velocity.
and v is the final velocity.
t represents time,
and a represents acceleration.
in this case,
a = 1.4 m/s²
u = 6 m/s
v = 13 m/s
hence,
1.4 = (13 - 6)/t
1.4t = 7
t = 7/1.4
t = 5 s
thank you!
