What is the average velocity of a car which moved a distance of 100km in 2 hours *?

Its average speed is 50 km/h.

What is the average velocity of a car that moved 80 km east in 2 hours?

40 km/h
The correct answer is 40 km/h. Distance travelled by car = 80 km. Then, Velocity is the distance travelled per unit of time.

What is average velocity example?

For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph). Average velocity, however, involves total displacement, instead of distance.

What is the average velocity of a car that moves 40 km east and 80km west in 2 hrs?

So after the car has moved 40 km [East] and then 80 km [West], its resultant displacement is 40 km [West]. So the average velocity of the car is 40 km [West] 2 hrs = 20 km/hr [West].

What is the average velocity of a car that moves 40 km east and 80km west in 2hrs?

What is the speed of a car if it traveled 100 kilometers in 2 hours?

values are given in the question, use the first formula: s=d/t = 100 km / 2 h = 50 km/h.

How much distance a car covers when it moves 20 km east and then 60 km west?

As distance does not depend on direction. Hence, Total Distance = (20 + 60) km = 80 km.

What is meant by average velocity?

Average velocity is the displacement of an object over time. To find the average speed of an object we divide the distance travelled by the time elapsed. We know that velocity is a vector quantity and average velocity can be found by dividing displacement by time.

What is an example of a journey with the same velocity?

Here are a few examples of journeys with the exact same displacement and time, and therefore the same average velocity: Anna walks west at 1 m/s for 2 seconds, then instantly accelerates to 3 m/s and keeps walking west for 2 seconds. Her total displacement is (1 m/s west) (2 s) + (3 m/s west) (2 s) = 8 meters west.

What is Bart’s average velocity and total displacement?

Her average velocity is 8m west / 4s = 2 m/s west. Bart walks west at 5 m/s for 3 seconds, then turns around and walks east at 7 m/s for 1 second. We can treat the eastward movement as “negative movement west,” so total displacement = (5 m/s west) (3 s) + (-7 m/s west) (1 s) = 8 meters. Total time = 4s.

How do you calculate average velocity with time and position?

(Technically Δs and Δt, or change in position and change in time, but you’ll be understood if you use s and t.) Average velocity v av is defined as s/t, so let’s put the formula in terms of s/t. v av = s/t = v i + ½at. Acceleration x time equals the total change in velocity, or v f – v i.

What is runner a’s average velocity?

Using the formula, we calculate v to be equal to (10+7.5) mph/ 2 giving us 8.75 mph as Runner A’s average velocity.
