Two spacecratfs from different nations have linked in space and are coasting with their engines off, heading directly toward Mars. The spacecrafts are thrust apart by large springs. Spacecraft 1, with a mass of 1.9x104 kg, then has a velocity of 3.5x103 km/h at 5.1 to its original direction. Spacecraft 2, whose mass is 1.7x104 kg, has a velocity of 3.4x103 km/h at 5.9 to its original direction. Determine the original speed of the two crafts when they were linked together
