Answer:
14.79 kgm/s
Explanation:
Data provided in the question
Let us assume the mass of baseball = m = 0.145 kg
The Initial velocity of pitched ball = 
= 47 m/s
Final velocity of batted ball in the opposite direction = 
= -55m/s
Based on the above information, the change in momentum is
= 14.79 kgm/s
Hence, the magnitude of the change in momentum of the ball is 14.79 kg m/s
Answer:
The measured value of the constant is known with some certainty to four significant digits. In SI units, its value is approximately 6.674×10−11 m3⋅kg−1⋅s−2. The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys.

Gamma rays are high frequency and are dangerous to our health. Ultraviolet rays come from the sun. Infrared waves are ones we experience every day, even though it is invisible to the naked eye. This is the heat we feel from the sun. </span>
