    Velocity
In summary, velocity is a measure of an object's rate of change in position over time. It can be calculated by dividing the change in distance by the change in time. To find a car's velocity in feet per second, you need to measure the distance traveled in feet and the time it took to travel in seconds. Various factors such as engine power, weight, road conditions, and driver's actions can affect a car's velocity. Velocity is different from speed, as it includes direction as well as magnitude. And finally, a car's velocity can change over time due to changes in speed, direction, or stopping.

For some reason i don't know why i can't get this problem:

A stunt driver travels a total distance of 1172 ft moving at a constant speed of 40 mph while weaving through an obstacl ecourse. If the total displacement of the car is 600 ft from the start of the course to the finish, determine the car's velocity

ANSWER: velocity = 30 feet/sec

but how did they get that?:confused:

Velocity is displacement over time. You have the displacement, so find the time. And next time, you should probably post a question like this in intro physics.
 

FAQ: Solve Velocity Problem: Find Car's Velocity in ft/sec

What is velocity and how is it calculated?

Velocity is a measure of the rate of change in an object's position with respect to time. It is calculated by dividing the change in distance by the change in time.

How do I find a car's velocity in feet per second (ft/sec)?

To find a car's velocity in ft/sec, you need to measure the distance the car has traveled in feet and the time it took to travel that distance in seconds. Then, divide the distance by the time to get the velocity in ft/sec.

What factors can affect a car's velocity?

A car's velocity can be affected by various factors such as the car's engine power, the weight of the car, the road conditions, and the driver's actions.

How is velocity different from speed?

Velocity and speed are often used interchangeably, but they are actually different. Velocity is a vector quantity that includes both magnitude (speed) and direction, while speed is a scalar quantity that only measures the magnitude.

Can a car's velocity change over time?

Yes, a car's velocity can change over time. This can happen if the car speeds up, slows down, changes direction, or stops. Any change in the car's speed or direction will result in a change in its velocity.
