Answer:
14.47 m/s
Explanation:
The momentum must be preserved before and after the collision:
The total momentum before the collision
where are the masses of the car moving south and north, respectively, before the collision.
is the velocity of the car moving South. We take the velocity to the North as the positive direction
The total momentum after the collision
where V = 5.22m/s is the velocity of both cars after the collision
We can equalize the 2 equations and plug in the numbers:
- Archimedes' principle states: An object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid.
- The PLIMSOLL LINE marked on the body of the ship acts as a guideline to ensure that the ship is loaded within the safety limit. A ship submerge lower in fresh water as fresh water density is lesser than sea water. Ships will float higher in cold water as cold water has a relatively higher density than warm water.
