Answer:
It depends on the climate and wind speed at the time.
If the climate is hot and no breeze it will move slower.
If it is cold and very windy it will move rapidly.
<span>A ball is thrown downward at 5ms from roof 10m high its velocity when it reaches the ground is 0 m/s. This is because it already dropped from the ground or x axis. So the velocity already stopped. </span>
Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.
