Answer:
1.67 m/s
Explanation:
Since this is an inelastic collision (the block and the arrow stick together after the collision), we can solve the problem by using the law of conservation of momentum:
where
is the mass of the arrow
is the initial speed of the arrow
is the mass of the block
is the initial speed of the block
is the final speed of the arrow+block
Substituting and re-arranging the equation, we find:
1)
4)
6)
7)
those are all examples of projectiles being in motion
Answer:
Explanation:
Volume ,V = 3 L
Initial temperature ,T₁ = 273 K
Initial pressure ,P₁ = 105 kPa
Final temperature ,T₂ = 381 K
Lets take final pressure =P₂
We know that ,If the volume of the gas is constant ,then we can say that
Now by putting the values in the above equation we get
Therefore the final pressure will be 146.53 kPa.
