a body of mass 25 gram has a momentum of 0.40 KG metre per second find its kinetic energy

Dear student It can be solve like this ok Momentum = mass × velocity 0.4 = 0.025 × v V = 0.4/0.025 V = 16 m/s To find the kinetic energy , KE = 1/2 m v^2 = 1/2 × 0.025 × 16 × 16 = 3.2 J Hence the kinetic energy=3.2 J regards
