The ends of a bar magnet are called poles. It has a north pole and a
south pole. To magnet two things, the poles must be linked oppositely. North to
south and south to north.
The car's (average) acceleration would be
The car's position over time would be given by
so that after 2.4 seconds, the car will have traveled a distance of
Answer: They’d fall at the same speed, because air resistance is the only thing that makes an object fall faster than another. There’s a video somewhere on the internet of a bowling ball and a feather falling at the same speed in a vacuum, if you look for it. Hope this helps!
Answer:
In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.
Explanation:
