A10 kg ball is traveling at the same speed as a 1 kg ball. compared to the 10 kg ball, the 1 kg ball has

1/100 the momentum
1/10 the momentum
the same momentum
ten times the momentum

A 10 kg ball is travelling at the same speed as a 1 kg ball. It has  1/10 the momentum when compared to the 10 kg ball

Option 2

Explanation:

If two objects travel with same speed, then the momentum can be calculated by the following,

Consider mass of 1 kg ball is

               for 10 kg ball as

Velocity is same for both so it is v

Momentum,

Then,

When substituting for v as , we get

From this, we know momentum of 1 kg ball is 1/10 times that of 10 kg ball.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
