100 N.s and 500 J
100 N.s and 1000 J
200 N.s and 500 J
200 N.s and 1000 J

UPSC CDS-2 – 2022
Given m = 10 kg and v = 10 m/s,
p = m * v = 10 kg * 10 m/s = 100 kg.m/s = 100 N.s.
– Kinetic energy (KE) is given by the formula 0.5 * m * v². The unit of kinetic energy is Joules (J).
Given m = 10 kg and v = 10 m/s,
KE = 0.5 * 10 kg * (10 m/s)² = 0.5 * 10 kg * 100 m²/s² = 5 * 100 J = 500 J.
Therefore, the linear momentum is 100 N.s and the kinetic energy is 500 J.
