### Understanding Rocket Propulsion in Space**Question:**Why must we use rocket propulsion systems in space, rather than another method to create the rocket's movement?**Answer Choices:**1. While usable, there are too few particles in space for a propeller to be as effective as we want.2. There is nothing to push off of in space, so you must throw stuff in the other direction to move forward.3. Rocket propulsion systems are the most durable and can handle coming in and out of Earth's atmosphere.4. Rocket propulsion systems are simply the most affordable and, therefore, help meet NASA's budget.**Concept Explanation:**In the vacuum of space, traditional propulsion methods such as propellers or jet engines that rely on atmospheric particles to generate thrust are not effective due to the lack of medium for the propeller to push against. Rocket propulsion, on the other hand, operates on Newton's Third Law of Motion: for every action, there is an equal and opposite reaction. In space, rockets expel mass (typically in the form of high-speed gas) in one direction, creating a thrust that propels the rocket in the opposite direction. This method does not depend on the presence of air or atmospheric particles, making it the essential mechanism for maneuvering in the vacuum of space.**Related Graphs/Diagrams:**For this educational content, consider including a diagram illustrating Newton's Third Law of Motion, specifically showing how expelling mass from a rocket nozzle generates thrust. Additionally, visual comparisons between a rocket in space and a propeller on Earth could help highlight the differences in propulsion mechanisms.

n IT'S ARMAGEDDON! A Texas sized asteroid is headed for Earth! You've been hired by NASA to be part of a misfit team of deep-core drillers to save the planet! As the engineer (and most educated person) on the team, you've been tasked with doing the calculations to make sure the Earth will be saved. The plan is to land on the 6.1 x 10²1 kg asteroid traveling at 9830 m/s and detonate a nuclear bomb. The asteroid will break into two pieces of equal mass. One piece will fly off at an angle of 30° and speed 9700 m/s. What will be the speed and angle of the second piece? Scientists estimate that as long as the angle is greater than 15° we're all gonna be alright!

33. Two blocks are free to slide along the frictionless, AMT Wooden track shown in Figure P9.33. The block of W mass m, = 5.00 kg is released from the position shown, at height h = 5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnct, which repels the north pole of an iden- tical magnet embedded in the back end of the block of mass l, 10.0 kg, initially at rest. The two blocks %3D never touch. Calculate the maximum height to which m, rises after the elastic collision. Figure P9.33
