Answer:
0.665
Explanation:
I did the work. Just plug everything in from the formula. Look at the lesson manual.
They compress or expand depending on amount of pressure or depending on the temperature
0.4 x 18 = 7.2 kg m/s
The momentum of the bottle after being hit is 0.2 x 25 = 5 kg m/s
7.2 - 5 = 2.2 kg m/s is the motmentum of the ball now
the velocity is 2.2/0.4 = 5.5 m/s
False, according to Boyle's law it's pressure increases, volume decreases
