1) You blast off from Mars, and you turn off the rockets when you are 3500 km (3.5 x 106 m) from the center of Mars, well above its thin atmosphere and headed away from the planet. You intend to leave Mars for good, and by the time you get very far away you want to be coasting at a speed of 1800 m/s. Mars has a mass of 6.4 × 1023 kg. a) Calculate the speed you must have when you are 3500 km (3.5 × 106 m) from the center of Mars in order that your speed when you are very far from Mars is 1800 m/s. Explain carefully and completely, starting from a fundamental principle (Momentum Principle or Energy Principle).

Question
Hello, I need some help with this problem?
Transcribed Image Text:1) You blast off from Mars, and you turn off the rockets when you are 3500 km (3.5 x 10°
m) from the center of Mars, well above its thin atmosphere and headed away from the planet. You
intend to leave Mars for good, and by the time you get very far away you want to be coasting at a
speed of 1800 m/s. Mars has a mass of 6.4 × 1023 kg.
a) Calculate the speed you must have when you are 3500 km (3.5 × 106 m) from the
center of Mars in order that your speed when you are very far from Mars is 1800 m/s. Explain
carefully and completely, starting from a fundamental principle (Momentum Principle or Energy
Principle).
