A20 gram bullet traveling at 250 m/s strikes a block of wood that weights 2kg with that weighs 2kg. with that velocity will the block and bullet move after the collision

velocity for block of wood 2.5 m/s and after collision, bullet and block do not move with this velocity.

Explanation:

In physics, the term “momentum” refers the object’s motion quantity. In simple, momentum (p) equals to the product of mass (m) and velocity rate (v)

Here, given:

Bullet mass = 20 gram = 0.20 kg

Bullet’s speed = 250 m/s

Mass for block of wood = 2 kg

Need to find velocity for block of wood  and whether they move after collision

The total momentum of the system before the collision equals the total momentum of the system after the collision. Thus,  

By substituting the given values, we get

No energy transformation and no change in momentum referred as elastic collision. When an object hits another object and bounce off each  other, the collision would be Elastic. So, concluding that with this velocity they would not move after collision.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
