DESPERATE
A small rocket ship with a mass of 1000 kg is resting on a Florida launch-pad. At 10 seconds, the engines ignite, producing a constant thrust of 100,000 N. The launch proceeds smoothly and rocket climbs vertically for another 10 seconds before the thrusters momentarily switch off for 5 seconds. Then a stronger thruster kicks in, producing a constant thrust of 200,000 N until it leaves the atmosphere several minutes later.
a. Draw a Free Body Diagram and label the forces acting on the rocket ship for each of the following times:
i. Time t = 0 to 10 seconds: Time t= 10 to 20 seconds:
ii. Time t = 20 to 25 seconds: Time t = 25 to 30 seconds:
