Aspacecraft's landing is cushioned by air bags. as it lands on mars, the velocity of downward fall is 20 meters/second. immediately after impact the velocity is 10 meters/second. if the spacecraft has a mass of 7.1 × 104 kilograms, what is the value of the impulse?

Thank you for posting your question here in . Below are the choices that can be found elsewhere.

A. 1.2 x 10^4
B. 2.2 x 10^5
C. 7.1 x 10^5
D. 3.6 x 10^4

The answer is C that means to say that the velocity after impact is still in the same direction as when the spaceship is falling.

Year  1936,  lehman predicted that the earths 'inner core' is solid. she observed that the seismic signals during her study were bent and did not pass through instead bouncing back. later it was confirmed that the earth's inner core was solid made up of nickel-iron and had a molten outer core.
