MCQ
Two unequal masses are tied together with a cord with a compressed spring in between. When the cord is burnt with a match releasing the spring, the two masses fly apart with equal
- AKinetic energy
- BSpeed
- ✓Momentum
- DAcceleration
✓
Answer
Correct option: C.
Momentum
Due to this the two masses fly apart and acquire veloatus in inverse momentum to their masses. Since the are formal forces zero they will fly apart with equal momentum.
