City b is south of city a, and the 200 mile trip by car takes 4 hours. the cities are 120 miles apart in a straight line. what is the velocity of a trip from city a to city b?

The velocity of a trip from City A to City B using the car is 50 miles per hour.

Explanation:

Given

200 mile trip by car takes 4 hours.

Distance between cities = 120 miles

Required:

What is the velocity of a trip from City A to City B?

To get the velocity of a trip from city A to B, we consider the parameter given for the car that travel 200 miles distance in 4 hours

Velocity = displacement ÷ time

Where displacement 200 miles

Time = 4 hours.

By substituton,

So, velocity= 200 miles ÷ 4 hours

Velocity = 50 miles ÷ hour

Velocity = 50 miles per hour

The velocity of a trip from City A to City B using the car is 50 miles per hour.

The answer is:  30 mph south.

We are given the displacement, so, if the car were able to travel in straight road (displacement), the velocity is: 30 mph south.

Calculations:

Therefore, the velocity is: 30 mph south.

Remember, velocity has always a direction while the speed is just a magnitude.

Have a nice day!

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

attach the statements so i can answer : )
