11. Momentum & Impulse / Intro to Center of Mass / Problem 11
A research balloon, equipped for atmospheric studies, is stationary at a high altitude above the Earth's surface. It has a total mass , including both the balloon and attached scientific instruments. For specific data collection, one instrument package, with a mass , needs to be lowered to a different altitude. This instrument package is allowed to slide down a rope at a speed v relative to the balloon. Calculate the velocity of the balloon relative to the Earth immediately after the package starts sliding. What happens to the balloon's velocity relative to the Earth if the instrument stops sliding?
