Answer:
Impulse, J = 2.1 kg-m/s
Explanation:
Given that,
Mass of baseball, m = 0.14 kg
It was approaching him at 50.0 m/s and, as a result, the ball leaves the bat at 35.0 m/s in the direction of the pitcher. We need to find the magnitude of Impulse delivered to the baseball.
The change in momentum is equal to the Impulse imparted to the ball i.e.
J = -2.1 kg-m/s
So, the Impulse delivered to the baseball is 2.1 kg-m/s
Answer:
Sagittarius A
At its center, surrounded by 200-400 billion stars and undetectable to the human eye and by direct measurements, lies a supermassive black hole called Sagittarius A*, or Sgr A* for short.
