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:
The force of gravity between two objects depends on mass of both objects and distance between their centres.
Explanation:
According to the Law of Gravitation,
Thus,
And,
Hence from above it is clear that Force of gravity between two objects varies <em>directly</em> with the mass of both objects and <em>indirectly</em> with the distance between their centres.
