A child with a mass of 23 kg rides a bike with a mass of 5.5 kg at a velocity of 4.5 m/s to the south. Compare the momentum of the child with the momentum of the bike.

See the comparison bellow

Explanation:

A child with a mass of 23 kg rides a bike with a mass of 5.5 kg at a velocity of 4.5 m/s to the south. Compare the momentum of the child with the momentum of the bike.

Step one:

given data

m1= 23kg

m2= 5.5kg

velocity of the child and the bike= 4.5m/s

Required

The momentum of the bike and that of the child is given bellow

Step two:

The momentum of the child

Pc=mv

Pc=23*4.5

Pc=103.5 kg⋅m/s

Step three:

The momentum of the bike

Pb=mv

Pb=5.5*4.5

Pb=24.75 kg⋅m/s

Its shows that the child has a higher momentum than the bike

the difference which is =103.5-24.75

=78.75kg⋅m/s

the answer for apex is the lowest
