If an athlete runs once around a track back to the starting line is her average velocity zero?
No, the average velocity is not zero. Average velocity is the total displacement divided by the total time taken. For one lap around the track, the athlete ends up back at the starting line, so the total displacement is not zero.
Is velocity an objects speed and direction of motion?
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
What Julie ran eight laps around her schools quarter-mile track in 18 minuets her average velocity was?
To find Julie's average velocity, we first need to determine the total distance she ran. 8 laps around a quarter-mile track is 2 miles (8 laps * 0.25 miles/ lap). Then, we can divide this distance by the total time to get her average velocity, which is 2 miles / 18 minutes = 0.11 miles per minute.
Julie ran eight laps around her schools quarter mile track in 18 minutes Her average velocity was m s?
Julie's average velocity was 5 m/s. (Velocity = distance / time = 8 laps x 0.25 miles per lap / 18 minutes = 5 m/s)
When you run around a track at 5 km h your velocity is constant?
Yes, if you run around a track at a constant speed of 5 km/h, your velocity is constant because velocity includes both speed and direction. As long as you maintain this speed and direction, your velocity remains constant.
What is the average weight for a 14 year old track runner?
45
Is it possible to run round an oval running track at constant velocity?
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
If an athlete runs once around a track back to the starting line is her average velocity zero?
No, the average velocity is not zero. Average velocity is the total displacement divided by the total time taken. For one lap around the track, the athlete ends up back at the starting line, so the total displacement is not zero.
Who is faster a soccer player or track runner?
track runner. Usain Bolt should be the most striking example
The speed of an object in a paticular direction?
The speed of an object does not, by definition, have a direction. Speed is defined as the total distance that an object travels divided by the time that it takes the object to travel that distance. A similar concept which does have a direction is velocity. Velocity is defined as the displacement of the object (how far it has moved from its original position and the direction in which it has moved) divided by the time during which it moved. The difference between these two concepts can also be explained in terms of a runner completing a lap around a quarter-mile track. If it takes the runner three minutes to complete the lap, the runner's speed is .25miles/3minutes. The runner's velocity, however, is zero. This is because the runner starts at the same place that they end (because the track is a loop) so that at the end of the 3minutes they are back where they started which makes their displacement zero.
Emily jogs 3 laps at the track to warm up. she jogs at 5mph. then she runs 3 more laps at 7 mph. what is true about her average speed and her average velocity?
Her average speed is greater than her average velocity.
Is velocity an objects speed and direction of motion?
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
How much running do you do in High School for Track and Field?
I'm a distance runner and I average around 40 miles per week.
What is the fastest boy track runner?
Wesley Paul is the fastest boy runner
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
A racetrack measures 5 miles long if an automobile completes the track in 4 minutes what is the average rate of speed in miles per hour?
The car's average speed is 75 miles per hour.
