Answer :
Answer:
[tex]\mathrm{v}_{2} \text { velocity after the collision is } 3.3 \mathrm{m} / \mathrm{s}[/tex]
Explanation:
It says “Momentum before the collision is equal to momentum after the collision.” Elastic Collision formula is applied to calculate the mass or velocity of the elastic bodies.
[tex]m_{1} v_{1}=m_{2} v_{2}[/tex]
[tex]\mathrm{m}_{1} \text { and } \mathrm{m}_{2} \text { are masses of the object }[/tex]
[tex]\mathrm{v}_{1} \text { velocity before the collision }[/tex]
[tex]\mathrm{v}_{2} \text { velocity after the collision }[/tex]
[tex]\mathrm{m}_{1}=600 \mathrm{kg}[/tex]
[tex]\mathrm{m}_{2}=900 \mathrm{kg}[/tex]
[tex]\text { Velocity before the collision } v_{1}=5 \mathrm{m} / \mathrm{s}[/tex]
[tex]600 \times 5=900 \times v_{2}[/tex]
[tex]3000=900 \times v_{2}[/tex]
[tex]\mathrm{v}_{2}=\frac{3000}{900}[/tex]
[tex]\mathrm{v}_{2}=3.3 \mathrm{m} / \mathrm{s}[/tex]
[tex]\mathrm{v}_{2} \text { velocity after the collision is } 3.3 \mathrm{m} / \mathrm{s}[/tex]
