Answer:
0.67 m/s
Explanation:
Mass of car 1, m₁ = 5000 kg
Mass of car 2, m₂ = 10,000 kg
Initial speed of car 1, u₁ = 2 m/s
Final speed of car 2, u₂ = 0 (at rest)
We need to find the final velocity of both cars when inelastic collision occurs. The momentum will remain conserved in case of inelastic collision. Using the conservation of momentum. Let V is the final speed.
So, after the inelastic collision, they will move with a speed of 0.67 m/s.
Answer:
is the density of the oil
Explanation:
Given:
- height of oil column,
- oil column height that is more than the water column height in the other arm,
<u>Now from the given it is clear that the height of water column is:</u>
Now according to the pressure balance condition of fluid columns:
Pressure due to water column = Pressure due to oil column
is the density of the oil
