Question

find the kinetic energy of the body mass 200gm moving at the speed of 2.0m/s

Answer 1

Given mass = 200gm

= 200/1000 kg
V= 2m/s

KE = 1/2mv^2

= 1/2×200÷1000×2×2
=0.4J

Answer 2

HERE IS YOUR ANSWER

kinetic energy = 1/2 × m ×v ^2

m = 0.2 kg

v = 2 m/s

kinetic energy = 1/2 × 0.2 × 4

= 0.4 J
