Given :
You fire a paintball from a paintball gun straight up into the air at 25.0 m/s.
To Find :
What is the ball velocity at the higher point that the ball reaches.
Solution :
We know, when ball is moving upward acceleration due to gravity is applied downward.
So, the ball will decelerate and when ball reaches maximum height its velocity will become zero.
Therefore, ball velocity is 0 m/s at maximum height.
Hence, this is the required solution.
DNA holds or genes, traits and we all have different amounts of chromosomes and that makes us different from other animals. A fishes genes would be different from ours because there DNA is different they have a different set of genes and chromosomes. Hop that Helped. we are genetically different.
It is b because more hurricanes form more when El Niño is present
Answer:
Yes
Explanation:
There was a force, 500 lb.
and a motion in the direction of the force, in this case a negative direction.
Therefore the lifter did negative work on the mass of the barbell against gravity.
Gravity would do positive work against the mass of weight when the lifter lowers the barbell as the force vector and the motion vector are in the same direction.
