The chart lists the masses of four balls that have the same momentum. A 2-column table with 4 rows. The first column labeled Ball Color has entries Green, Red, Yellow, Purple. The second column labeled Mass (kilograms) has entries 0.5, 1.2, 0.9, 1.7. Which correctly compares two of the balls? The green ball has a lower velocity than the purple ball. The red ball has a greater velocity than the purple ball. The yellow ball has a higher velocity than the green ball. The red ball has a greater velocity than the green ball.

The red ball has a greater velocity than the purple ball

Explanation:

Given the chart :

Ball : Green - - - Red - - - Yellow - - - Purple

Mass : 0.5 - - - - - - 1.2 - - - - - 0.9 - - - - - - 1.7

The four balls have the same momentum

Momentum = mass × velocity

Since momentum is directly proportional to the product of Mass and velocity, and the balls have the same momentum. Therefore the lower the mass of the ball, the higher or greater it's Velocity.

Because if the balls with lower masses have lower Velocities than balls with higher masses, both balls cannot have the same momentum.

Therefore, the only viable option above is, The red ball has a greater velocity than the purple ball, because the red ball has a lower mass than the purple 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.
