Answer: 10.3m/s
Explanation:
In theory and for a constant velocity the physics expression states that:
Eq(1): distance = velocity times time <=> d = v*t for v=constant.
If we solve Eq (1) for the velocity (v) we obtain:
Eq(2): velocity = distance divided by time <=> v = d/t
Substituting the known values for t=15s and d=155m we get:
v = 155 / 15 <=> v = 10.3
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.
