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.
