Answer:

See Below

Explanation:

Mass of child = 21 kg

Mass of bicycle = 5.9 kg

Total mass = 22 + 5.9 = 27.9 kg

Velocity = 4.5 m/s

1) Total momentum of the child and the bike together

= Total mass * Velocity

= 27.9*4.5

= 125.55 kg m per second

2) Momentum of the child

= Mass of child*Velocity

= 21*5.9

= 123.9 kg m per second

3) Momentum of the bike

= Mass of bike*Velocity

= 5.9*4.5

= 26.55 kg m per second
