Answer:
3000 J
Explanation:
Kinetic energy is:
KE = ½ mv²
If m = 15 kg and v = -20 m/s:
KE = ½ (15 kg) (-20 m/s)²
KE = 3000 J
Answer:
the answer from my side is both vertical and horizontal
Regular trains follow train tracks and travel on rails; Maglev trains are Magnetically Levitated using powerful electromagnets, so that they actually hover slightly above the ground. This massively reduces friction and allows them to travel much faster (kind of like how a puck can go really far with only a little push on an air hockey table).
It slows down. The molecules/particles aren't as close together, resulting in slower movement.
