1. A Starlink satellite, which is part of a network to provide Internet access all over the world, is launched on a Falcon 9 two-stage-to-orbit rocket. During its first stage, the Falcon 9 rocket accelerates from rest to a velocity of 2.119 m in about 163s before separating. What was the acceleration of the Falcon 9 rocket during its first stage? 2. After the first stage separates from the Falcon 9 rocket, it begins its descent. This descent begins 40 after the launch and concludes 523s after the launch. The initial velocity of the descent is 2.184 , and its final velocity is -7.7", A What is the acceleration of the first stage? B Are the signs of the final velocity and acceleration the same or different? C Does the first stage speed up or slow down as it descends? 3. While in the middle of a flight, a small piece of a rocket comes off and begins to plummet back down to Earth. As it falls, its acceleration is -9.81 ". ". It takes 120s for it to reach the ground and, when it was attached to the rocket, it was moving with a velocity of 1, 000 .. A How fast was it moving right before hitting the ground? B Are the signs of the final velocity and acceleration the same or different
