Answer:
Explanation:
Both carts are modelled by using the Principle of Energy Conservation and Work-Energy Theorem:
Cart A:
By assuming a constant acceleration, final velocity is equal to:
Then,
Cart B:
By assuming a constant acceleration, final velocity is equal to:
The kinetic energy of cart B is 0.5K.
The answer is C. 15 meters North
Displacement is the distance and direction from the origin. If you move 20 meters North, your displacement is 20 meters North. If you move 5 meters South, you are basically moving back the way you came by 5 meters, which means you are now 15 meters North.
I hope this helped! :)
