Question

Space with an initial rightward velocity of 300 m/s. Then, an explosive charge spacecraft, pushing them apart exactly along the direction of the spacecraft's motion. rightward velocity of 350 m/s. (Assume that all objects move only along a rge spacecraft consists of two unequal-mass portions: 50 000 kg and 250,000 kg, respectively. The entire spacecraft is moving in distant outer separates the two halves of the spacecraft, pus Afterward, the larger portion has a final single line, and that there is no 2-D motion. a. What is the final velocity of the smaller b. Wh an initia velocity Assume 2 significant figures on all values.) portion of the spacec at is the total ang in kinetic energy of the system? Is this explosion elastie or inelastic

Explanation / Answer

initial momentum = 300,000*300 m/s

final momentum = 250,000*350+ 50,000*X

as per conservation of momentum,

300,000*300 = 250,000*350+ 50,000*X

X = 50 m/s towards right

kinetic energy inital = 1/2*mV^2 = 1.35*10^10

kinetic energy final = 1/2*m1V1^2 +1/2*m2V2^2 = 1.531*10^10

inelastic explosion

*please post other questions as seperate queries*

8. the same as

9. floor is frictionless, hence kicking wont work, howling is the only option available
