Question

1. the force of a moving object is called momentum. the momentum of an object is proportional to its weight and speed. the more momentum it has, the more force. so if there were two cars, both the same model, and one of the cars was traveling 30 mph faster than the other, which car has more force?

a. the slower car
b. the faster car
c. both cars have equal force
d. none of the above

Explanation:

Question 28

This is a question about DMV (Department of Motor Vehicles) regulations regarding address changes. In many regions, the requirement is to notify the DMV of an address change within 30 days.

In urban areas, intersections are high - risk areas for accidents due to the convergence of multiple traffic streams (different directions of vehicles, pedestrians, etc.). So most accidents in urban areas occur at intersections.

Momentum ($p$) is given by the formula $p = mv$, where $m$ is mass and $v$ is velocity. The two cars are of the same model, so they have the same mass ($m$). One car is faster (higher $v$) than the other. Since momentum is proportional to velocity when mass is constant, the faster car will have more momentum (and thus more force related to its motion as per the problem's description of momentum being related to force).

Answer:

A. 30
