Question 26

Multiple Choice

Two objects, one of mass m<sub>1</sub> = 2 kg and the second of unknown mass, are connected by a compressed spring with negligible mass. The system is at rest on a frictionless table. Both objects are released simultaneously, and m<sub>1</sub> is observed to recoil with velocity v<sub>1</sub> = 2 m/s , and m<sub>2</sub> shots forward with velocity v<sub>2</sub> = 4 m/s . What is the mass of m<sub>2</sub>? A) 0.5 kg B) 1 kg C) 2 kg D) 4 kg E) Cannot be determined.
