## Question:

A 10 kg cart was observed moving north with a speed of 15 m/s before it collided with an identical cart moving south at 10 m/s. The collision was observed to cause the carts to couple and move together as one. What is in kg m/s the combined momentum of both carts before the collision?

## Collision:

When the two objects are moving means having the momentum collides with one-another then stick as one unit after the collision, such collisions are known as Inelastic collision.

Given

Mass of the cart (m) = 10 kg

The velocity of the cart 1 {eq}(u_{1}) = 15 \ m/s {/eq}

Velocity of the cart 2 {eq}(u_{2}) = -10 \ m/s {/eq}

...

Any moving object has momentum, but how much momentum it has depends on its mass and velocity. In this lesson, you'll identify linear momentum, as well as see examples of how an object's momentum is affected by mass and velocity.
