Adding Mass to a Moving System Practice Problems

A humanitarian helicopter of total mass 11 500 kg (pilots and food boxes) releases vertically a 150 kg box of food. The helicopter is flying at a constant speed of 45 m/s in the x-direction. Find the box's velocity immediately after it was released.

A bus of mass M traveling at a velocity of + V Î crashes into a truck of mass 4M traveling at a velocity of + V/4 Î and sticks to it. Just after, the bus and the truck collide with a car of mass M/2 waiting at a red light. Find the velocity of the bus, truck, and car after the collision if they stick together.

A container ship weighing around 20,000 kg was moving at a speed of 3.0 m/s when suddenly an extra load weighing around 5000 kg was added to it abruptly. What would be the speed of the ship after loading?

A truck with a mass of 9000 kg is moving at a constant velocity of 20 m/s. A sandbag weighing 1000 kg initially stationary falls vertically and lands in the back of the truck. What is the new velocity of the truck after catching the sandbag?
