A 4.25 g bullet traveling horizontally with a velocity of magnitude 375 m/s is fired into a wooden block with mass 1.10 kg , ini

tially at rest on a level frictionless surface. The bullet passes through the block and emerges with its speed reduced to 122 m/s.
How fast is the block moving just after the bullet emerges from it?

Answer:

block is moving at 0.97m/s after the bullet emerges from it

Explanation:

The problem is based on elastic collision

Given data

Mass of bullet m1= 4.25g to kg we have 4.25/1000= 0.00425kg

Mass of block m2= 1.10kg

Initial velocity of bullet u1= 375m/s

Initial velocity of block u2= 0m/s

Final velocity of bullet v1= 122m/s

Final velocity of block v2=?

To solve for the final velocity of the block let us apply the principles of conservation of momentum for an elastic collision

m1u1+m2u2=m1v1+m2v2

Substituting our data into the

expression we have

(4.25*10^-3*375)+(1.1*0) =

(4.25*10^-3*122) + (1.1*v2)

1.59+0=0.52+1.1v2

1.59-0.52=1.1v2

1.07=1.1v2

v2=1.07/1.1

v2= 0.97m/s

What is the most likely reason that Mendeleev placed tellurium before iodine?
Ilya [14]
Mendeleev watched that tellurium has compound properties like different components in its gathering, and he didn't realize that neutrons cause the more noteworthy nuclear mass. Mendeleev expressed that he anticipated that tellurium would have a lower nuclear mass than iodine.

In which phase of mitosis are chromosome first seen as a result of chromatin coiling?
Kruka [31]
<span>Mitosis is a a means for cells to split and produce exact copies of themselves. The process produces two identical copies of the original cell and occurs throughout the human body. Mitosis is divided up into four main phases known as prophase, metaphase, anaphase and telophase. The chromosomes first become visible in early prophase.</span>
