An astronaut with a mass of 85 kg is outside a space capsule when the tether line breaks. to return to the capsule, the astronaut throws a 2.0 kg wrench away from the capsule at a speed of 14 m/s. at what speed does the astronaut move toward the capsule?
In this case momentum is conserved and therefore; M1V1 =M2V2 M1 = 85 kg, V1 = ?, M2 = 2 kg, V2 = 14 m/s 85 kg × V1 = 2 kg × 14 m/s 85 V1 =28 V1 = 0.3294 m/s Therefore; the speed of the astronaut towards the capsule is 0.3294 m/s
