Answer:
The velocity of other mass is 3.60 m/s.
Explanation:
Given that,
Mass of first block = 8 kg
mass of second block = 4.3 kg
Speed = 6.7 m/s
We need to calculate the speed of first mass
Using conservation of momentum
[tex](m_{1}+m_{2})u=m_{1}v_{1}+m_{2}v_{2}[/tex]
where, m₁ =mass of first block
m₂ =mass of second block
m₁ =mass of first block
v₂ =speed of second block
Put the value into the formula
[tex]8+4.3\times0=8\times v_{1}+4.3\times6.7[/tex]
[tex]v_{1}=\dfrac{-4.3\times6.7}{8}[/tex]
[tex]v_{1}=-3.60\ m/s[/tex]
Negative sign represent the opposite direction of initial value.
Hence, The velocity of other mass is 3.60 m/s.
