A7.0-kilogram cart, a, and a 3.0-kilogram cart, b, are initially held together at rest on a horizontal, frictionless surface. when a compressed spring attached to one of the carts is released, the carts are pushed apart. after the spring is released, the speed of cart b is 6.0 meters per second, as represented in the diagram belowwhat is the speed of cart a after the spring is released?

The speed of cart A after the spring is released is 2.57 m/s.

Given the following data:

To find the speed of cart A after the spring is released, we would apply the law of conservation of momentum:

Where:

Substituting the given parameters into the formula, we have;

Note: The negative sign indicate that cart A is moving to the left direction.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
