Answer :
Answer:
The velocity of 5 kg object is 9 m/s.
Explanation:
Given that,
Mass of object = 15 kg
Velocity of object = 3 m/s
Mass of second object = 5 kg
We need to calculate the velocity of second object
Using conservation of momentum
[tex]m_{1}v_{1}=m_{2}v_{2}[/tex]
[tex]v_{2}=\dfrac{m_{1}v_{1}}{m_{2}}[/tex]
Where, [tex]m_{1}[/tex]=mass of first object
[tex]m_{2}[/tex]=mass of second object
[tex]v_{1}[/tex]=velocity of first object
Put the value into the formula
[tex]v_{2}=\dfrac{15\times3}{5}[/tex]
[tex]v_{2}=9\ m/s[/tex]
Hence, The velocity of 5 kg object is 9 m/s.
