Explanation:
If you do B, the wagon slows down due to friction

The outer rigid layer of the earth is divided into a couple of dozen “plates” that move around across earths surface relative to each other.
3.33 seconds.
<u>Explanation:</u>
We can find the speed of the body using the formula,
Speed = Distance traveled in meters / time taken in seconds
= 450 m / 30 seconds
= 15 m/s
So per second the distance traveled by the body is 15 m.
So time needed to travel 50 m can be found as,
time = distance/speed
= 50 m / 15 m /s
= 3.33 s
