Two balls each of mass 250 g moving in opposite directions each with a speed \(16 \mathrm{~m} \mathrm{~s}^{-1}\) collide and rebound with the same speeds. The impulse imparted to one ball due to the other is
- A \(4 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}\)
- B \(16 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}\)
- C \(8 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}\)
- D \(2 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}\)
Answer & Solution
Correct Answer
(C) \(8 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}\)
Step-by-step Solution
Detailed explanation
\(m = 250 \mathrm{~g} = 0.25 \mathrm{~kg}\) \(J = m(v - u)\) \(J = 0.25 \mathrm{~kg} (-16 \mathrm{~m} \mathrm{~s}^{-1} - 16 \mathrm{~m} \mathrm{~s}^{-1})\) \(J = 0.25 \mathrm{~kg} (-32 \mathrm{~m} \mathrm{~s}^{-1})\) \(J = -8 \mathrm{~kg} \mathrm{~m} \mathrm{~s}^{-1}\) Magnitude…
