<u>Answer:</u> The ball is travelling with a speed of 5.5 m/s after hitting the <u>bottle.</u>
<u>Explanation:</u>
To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:
where,
are the mass, initial velocity and final velocity of ball.
are the mass, initial velocity and final velocity of bottle.
We are given:
Putting values in above equation, we get:
Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.
Answer:
The final pressure of oxygen gas is 8.33 atm.
Explanation:
From the given data
V=26 m^3 or 26000 L
T1=270K
T2=440K
n1=6000 moles
R=0.0821 L.atm/molK
Now from the ideal gas equation
As the options given are not defined in which unit thus the final pressure of oxygen gas is 8.33 atm.
