The FIRST statement on the list is the definition of momentum, so that's the one that must be true.
Answer:
an example for applied force is
Explanation:
The applied force is the force applied to the object to either displace it or change its shape.
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
![m_1u_1+m_2u_2=m_1v_1+m_1v_2](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3Dm_1v_1%2Bm_1v_2)
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
![m_1=m_2=M](https://tex.z-dn.net/?f=m_1%3Dm_2%3DM)
Initial velocity of ![m_1=u_1=2 m/s](https://tex.z-dn.net/?f=m_1%3Du_1%3D2%20m%2Fs)
Initial velocity of
(opposite direction)
Final velocity of
(same direction )
Final velocity of
(same direction)
![M\times 2 m/s+M(-1 m/s)=Mv+Mv](https://tex.z-dn.net/?f=M%5Ctimes%202%20m%2Fs%2BM%28-1%20m%2Fs%29%3DMv%2BMv)
![1 m/s=2v](https://tex.z-dn.net/?f=1%20m%2Fs%3D2v)
v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
Answer:
A. limestone
Explanation:
Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water.
Answer:
60 seconds.
Explanation:
2400 divided by 40 equals 60
