a. What is the velocity of the rocket when the engine shuts off? Ans: ( )
b. How long, after the rocket shuts down, is the velocity of the rocket down ? Ans:

Isn’t it fascinating how physics and rocket science coalesce into a spectacular display? In the historical race to the skies, model rockets ignite a passion that harkens back to the early pioneers of rocketry like Robert Goddard, who launched the first liquid-fueled rocket in 1926. This bold mission propelled us into an age of exploration and discovery, much like our own small-scale experiments with model rockets.

Now, let’s ensure we ditch those pesky missteps while timing the rocket’s descent! One common mistake is neglecting to separate the two phases of the flight: powered ascent and free fall. Ensure you calculate the time during each phase distinctly. Remember, after the engine cuts off, the only force acting on the rocket is gravity, which slows it down at . Keep track of your units, and you’ll be flying high without any snags!
