1.5: The Falcon 9 rocket version 1.2 that Elon Musk calls the "Full Thrust" version has a total initial takeoff thrust of 7607 kN (kilo-Newtons, each of which is 1000 N) from its first-stage rocket engines at sea eve. The vehicle has a mass of 549.054 metric tons on takeoff (a metric ton is 1000 kg or 2200 lb, which turns out to be pretty close to an Imperial ton, which is 2000 Ib). What is the rocket's acceleration as it takes off from its launch pad? (10 points) 1.6: NASA's Cassini spacecraft arrived at Saturn on 2004 July 1. It had to then slow down to enter into Saturn orbit and not just keep flying by into interplanetary space. Simplifying the actual maneuver somewhat, take Cassini's mass to be a constant 4500. kg. Assume that its initial velocity was 24.26 kilometers per second. The rocket burn slowed Cassini's velocity by 622 meters per second. How much work did the rocket do in slowing Cassini into orbit?
