The answer is C. 35m/s because there is no direction
The correct answer is A) <span>The two magnetic fields repel each other, causing the train to levitate, or hover, above the rails.
In fact, same magnetic poles repel each other, while opposite magnetic poles attract each other. the magnets on bottom of the train and on top of the railway have the same polarities, so they repel each other and this allows the train to levitate.

Answer:
D. 200 kgm/s
Explanation:
Momentum is conserved.
Initial momentum = final momentum
(50 kg) (4 m/s) + (30 kg) (0 m/s) = final momentum
200 kgm/s = final momentum
Answer:
I think the answer is 100 watts
Answer:
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
