Explanation:
Let the mass of two objects be m. Both objects move along the same line in opposite directions. Let v and u₂ are speeds of both objects before collision.
After the collision, both objects stick together and move with the speed of 0.1 V the direction of the velocity of the first mass before the collision.
Using the conservation of momentum as :
![m_1u_1+m_2u_2=(m_1+m_2)v](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3D%28m_1%2Bm_2%29v)
![V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7Bm_1u_1%2Bm_2u_2%7D%7B%28m_1%2Bm_2%29%7D)
On solving above equation, ![u_2=-0.8v](https://tex.z-dn.net/?f=u_2%3D-0.8v)
So, the speed of the second mass before the collision is 0.8 v. The negative sign shows that the it moves in opposite direction. Hence, this is the required solution.
The bowling ball will require more force to roll because it is more massive.
If the substance doesn't change chemically, it is a physical reaction.
Answer:
Explanation:
Explanation: total displacement =3√2m. and total distance covered=14m. I hope this is right and helps u.
Scott needs to determine the density of a metallic rod. First, he should determine the mass of his sample on the laboratory balance. Second, he should measure the volume of his sample by water displacement. Finally, he can calculate the density by dividing mass/volume.
Hope this helped ;)
