Answer:
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
