Physics

To solve this, we'll use the principle of conservation of momentum. Since the truck and car collide inelastically and stick together, the total momentum before the collision is equal to the total momentum after the collision.

 

The formula for momentum conservation is:

 

Where:

(mass of the truck)

(velocity of the truck)

(mass of the car)

(velocity of the car, negative because it is moving in the opposite direction)

is the final velocity of the combined system after the collision.

 

Now, substitute the known values into the equation:
