Question

A 70.0Kg cyclist Rides a 15.0kg

mountain Bike with a Speed of
15m/s Calculate the magnitude
of the momentum of the Bike-rider
system Round your answer to the nearest hundred

Answer 1

`1275 kg*m/s`

Step-by-step explanation:

We'll use the momentum equation:

`p=mv`

where:

p = momentum

m = mass

v = velocity

Since we're doing the magnitude of momentum of the system, we'll add the mass of the cyclist and the mountain bike together:

`70.0 kg + 15.0kg=85.0 kg`

Given that, we can now substitute our given values into the momentum equation:

`p=mv\\p=85.0kg*15.0m/s`

Our final answer is:

`p= 1275 kg*m/s`
