A body of mass 2 kg moves with a velocity of 5 m s−1. Calculate its momentum and its kinetic energy.
Original Khojo Papers practice question — not from a past board paper.
Answer
Momentum = 10 kg m s−1 and kinetic energy = 25 J
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Momentum = mv = 2 × 5 = 10 kg m s−1. Kinetic energy = ½mv2 = ½ × 2 × 25 = 25 J.
