Please help! :)
A spacecraft which weighed 1,500.0 pounds on earth is traveling in deep space at a constant velocity of 100,000.0 ft/sec. Ground control wants to initiate a rocket burn that will accelerate the spacecraft 500.0 ft/sec^2.
What is the mass in slugs of the spacecraft?
What is the force of that rocket burn?

Best ResponseYou've already chosen the best response.1A slug is equal to 32.174 pound mass (a pound mass weighs 1 pound on earth) so a 1500 lb. weight on earth would be 1500/32.174 =46.62 slugs. Newtons Second Law; force=mass*acceleration. Since we are given the acceleration in ft/sec^2 and the mass is given in slugs the unit of force will be pounds. In this case the force is 46.62slugs*500ft/sec^2=23310.7 pounds of thrust. The spacecrafts current velocity is extraneous information.
