1.) You are in a spaceship at rest in deep space, outside the influence of any gravity. Without fuel, your vessel has a mass of 5,750 kg and its rocket engine expels exhaust at a speed of 8,250 m/s. You want to travel to an outpost that is quite far away, and you decide to accelerate to a speed of 12,500 m/s, coast for some time, and then slow down to a stop. A) What is the minimum mass of...

An experimental space cruiser was initially drifting in the −x direction with velocity of 10 m/s. The ion thrusters on the cruiser then fires and provides +5x10^4N of force on the cruiser for 15 seconds. If the spaceship has a mass of 11,000 kg, what will its final velocity along the +x direction be? a. -5.8m/s b. +5.8m/s c. +86m/s d. +7.8m/s e. -64m/s f. -6.8m/s The answer I got was 58.18 m/s, have I done something wrong?

Part A A 3.7 x 1010 kg asteroid is heading directly toward the center of the earth at a steady 20 km/s. To save the planet, astronauts strap a giant rocket to the asteroid perpendicular to its direction of travel. The rocket generates 5.0 x 10° N of thrust. The rocket is fired when the asteroid is 4.9 x 106 kmaway from earth. You can ignore the rotational motion of the earth and asteroid around the sun. If the mission...
