Your friend of 50 kg is riding a motorcycle of mass 250 kg at 20 m/s. Can you figure out the momentum?

Momentum ($𝑝$) is calculated using the formula:

$𝑝=𝑚𝑣$

where $𝑚$ is the mass and $𝑣$ is the velocity.

In this scenario:

• The total mass $𝑚$ is the sum of the mass of the rider and the mass of the motorcycle.
• The mass of the rider is 50 kg.
• The mass of the motorcycle is 250 kg.
• The velocity $𝑣$ is 20 m/s.

First, we calculate the total mass:

${𝑚}_{\text{total}}=50\text{kg}+250\text{kg}=300\text{kg}$

Next, we calculate the momentum:

$𝑝={𝑚}_{\text{total}}\times 𝑣$ $𝑝=300\text{kg}\times 20\text{m/s}$ $𝑝=6000\text{kg}\cdot \text{m/s}$

So, the momentum of the motorcycle and the rider is $6000\text{kg}\cdot \text{m/s}$.
