Question

1. 1998, NASA launched Deep-Space 1 (DS-1), a spacecraft thatsuccessfully flew by the asteroid named 1992 KD (which orbits thesun millions of miles from the earth). The propulsion system ofDS-1 worked by ejecting high-speed argon ions out the rear of theengine. The engine slowly increases the velocity of DS-1 by about19.0 m/s per day. a) How much time (in days) would it take to increase thevelocity of DS-1 by12200 m/s?
Enter a number. _____ days

What was the acceleration of DS-1 (in m/s2)?
Enter anumber ____m/s2 a) How much time (in days) would it take to increase thevelocity of DS-1 by12200 m/s?
Enter a number. _____ days

What was the acceleration of DS-1 (in m/s2)?
Enter anumber ____m/s2

Explanation / Answer

Increse rate of speed v = 19 m /s per day (a). Final speed v ' = 12200 m / s time t = v ' / v           =642.105 days (b). Accleration a = ( v ' - v ) / t                           = 19 m / s ^ 2
