In the great shopping cart race, two students push on shopping carts. a having twice the mass of b, with the same force applied over the same distance. which shopping cart wins the race? a. cart a b. cart b c. neither, its a tie

B. cart B

Explanation:

The acceleration of each cart is given by Newton's second law:

where F is the force applied, a is the acceleration and m is the cart's mass.

The force F applied is the same for the two carts, however the mass of cart A (mA) is twice than the mass of cart B (mB), so we can rewrite the two accelerations:

we see that the acceleration of cart B is twice the acceleration of cart A, therefore cart B will move faster and will win the race.

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.
