suppose two vehicles collide to each other them after collision which quality remain contant?
Answers
Answer:
Explanation:
Given : two vehicles collide to each other
To Find : after collision which quantity remains constant
1.Force
2.Velocity
3.Displacement
4. Total Momentum
Solution:
Conservation of momentum is used here
Hence total momentum remains constant
mass of 1st vehicle = m₁
mass of 2nd vehicle = m₂
Velocity of 1st vehicle before collision = u₁
Velocity of 2nd vehicle before collision = u₂
Velocity of 1st vehicle after collision = v₁
Velocity of 2nd vehicle after collision = v₂
Total Momentum before collision = m₁u₁ + m₂u₂
Total Momentum after collision = m₁v₁ + m₂v₂
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
Total Momentum remains constant.
