Given information :


Mass ( m ) = 200 g

                 = 200 / 1000 kg

                 = 0.2 kg


Velocity ( v ) = 50 cm/s

                     = 50 m / 100 s

                     = 1 / 2 m/s

                     = 0.5 m/s


Formula :


Kinetic energy = 1/2 m v²

                         = 1/2 × 0.2 kg × ( 0.5 m/s )²

                         = 0.5 × 0.2 kg × 0.25 m²/s²

                         = 0.025 kg m²/s²

                         = 0.025 J


ANSWER :

The kinetic energy will be 0.025 J


Thanks for the question !!

Mass of the object (m)                     = 200 g

                                                         = 0.2 kg

velocity of the object (v)                  = 50 cm/s

                                                         = 0.5 m/s

Kinetic energy of the object (K.E)   = ?


formula

                              K.E = 1/2 mv²

                                      = 1/2 × 0.2× 0.5

                                      = 0.5×0.2×0.5

                                      = 0.05 J


           ∴   K.E = 1/2mv² = 0.05 J


hope it heip you
