if a motorcycle, a car, and a big rig are all moving with a velocity of 100 km/h, which vehicle has the greatest momentum?

if a motorcycle, a car, and a big rig are all moving with a velocity of 100 km/h, which vehicle has the greatest momentum?

Answer

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity.

Step2: Compare masses

Given that $v$ is the same ($100$ km/h) for the motorcycle, car and big - rig. The mass of a big rig is greater than the mass of a car, and the mass of a car is greater than the mass of a motorcycle.

Step3: Determine greatest momentum

Since $p = mv$ and $v$ is constant, the vehicle with the greatest mass will have the greatest momentum. The big rig has the greatest mass among the three, so it has the greatest momentum.

Answer:

The big rig
