Question:
Two spacecraft from different nations have linked in space and are coasting with their engines off, heading directly toward Mars. The spacecraft s are thrust apart by large springs. Spacecraft 1, with a mass of 1.9 x 10^4 kg, then has a velocity of 3.5 x 10^3 km/h at 5.1 degrees to its original direction (Figure 7.7). Spacecraft 2, whose mass is 1.7 x 10^4 kg, has a velocity of 3.4 x 10^3 km/h at 5.9 degrees to its original direction. Determine the original speed of the two craft when they were linked together.
Equations:
m1v1i + m2vi = m1v1f + m2v2f
I honestly tried attempting this but I got a completely wrong answer, can someone at least help guide me in the right direction. It would be much appreciated, thanks
