Answer:
the car with the hay should slow to 16m/s if the bale of hay is dropped into it.
The velocity of the bale of hay inside the car is 16m/s.
What is linear momentum?
The linear momentum of a body can be defined as the product of its mass and velocity.
Let,
the mass of rail loaded car is 'm₁'= 2000kg
the mass of the bale of hay is 'm₂'=500kg
the initial velocity of a railroad car on the track is 'v₁,=20m/s
the initial velocity of a bale of hay is 'v₂'=0m/s
The final velocity of the railroad car and a bale of hay together is 'V'
By using conservation of linear momentum
V=[tex]\frac{m1v1+m2v2}{m1+m2 }[/tex] ⇒16m/s
Since the bale of hay is in the car both will have the same velocity i.e 16m/s.
What is a linear momentum example?
If we are standing at the bottom of a hill and we are faced with the option of stopping a bike or a bicycle, then we will probably choose to stop the bicycle. The reasoning behind this is that the bike has more momentum than the bicycle. Here, momentum simply means the mass in a moving body.
