1. Space probes may be separated from their launchers by exploding bolts. (They bolt away from one another.) Suppose a 4100-kg satellite uses this method to separate from the 1200-kg remains of its launcher, and that 3000 ] of kinetic energy is supplied to the two parts. Assume that the satellite and launcher are at rest before separation and the direction of the satellite's velocity after separation is positive. Gravity is negligible compared to the force of explosion. Consider: Let the subscripts / and f denote the initial and final velocities and the subscripts s and / denote the satellite and the launcher, respectively. How many knowns are there and how many unknowns? satellite satellite launcher launcher Before launch After launch (a) For the system of space probes and launcher, is the force of the exploding bolts: O Internal O External (b) Is momentum conserved in this case? O Yes, momentum is conserved because no external forces act on the system. O No, momentum is not conserved because the force of the expanding bolts is present. (c) What is the KE of the system after separation? KE d) Solve for their subsequent velocities. Hint: How many equations do you need to solve for the unknowns? Can you identify and set-up the equations? Vm/s Vm/s
