Question

A child riding a bike has a total mass of 60kg. What is the momentum of the child-bike system if the child rides a distance of 200 m in 5 seconds at a constant speed?

Answer 1

Momentum = 2,400 Pa

Step-by-step explanation:

Given:

Total mass = 60 kg

Distance travel = 200 m

Time = 5 sec

Find:

Momentum

Computation:

Velocity = Distance / time

Velocity = 200 / 5

Velocity = 40 m/s

Momentum = Mass x Velocity

Momentum = 60 x 40

Momentum = 2,400 Pa
