Suppose the total momentum of two masses before a collision is 100 k m/s. what is the total momentum of the two masses after they collided.

Look up the Law of the Conservation of Momentum

A.) O kg m/s

B.) 50 kg m/s
C.) 100 kg m/s
D.) 200 kg m/s

Ok, so if it was 100 kg m/s before then according to the conservation of momentum it must be...

100 kg m/s ??

Spot on :)

To determine the total momentum of two masses after a collision, we need information about the masses and velocities of the objects involved. Without this information, we cannot provide an exact answer. However, I can explain the concept and provide you with a general formula for calculating momentum.

The momentum of an object is the product of its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction. The equation to calculate momentum is:

Momentum (p) = mass (m) * velocity (v)

For a two-object collision, let's define the masses as m1 and m2, and the velocities as v1 and v2. The total momentum before the collision is given as 100 k m/s.

Total initial momentum = m1 * v1 + m2 * v2

After the collision, the total momentum can be calculated using the same equation:

Total final momentum = m1 * v1' + m2 * v2'

Note that the primed velocities (v1' and v2') represent the velocities of the objects after the collision.

The principle of conservation of momentum states that in a closed system, the total momentum before the collision is equal to the total momentum after the collision. This means:

Total initial momentum = Total final momentum

Using this principle, we can solve for the final momentum, given the initial momentum and appropriate values for masses and velocities.

So, to calculate the total momentum of two masses after they collide, we need the masses and velocities of both objects before and after the collision.
