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
  • A
    Kinetic energy
  • B
    Speed
  • C
    Momentum
  • D
    Acceleration
✓

Answer

  1. Momentum

Explanation:

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.
