What is the displacement of a NASCAR stock car after he completes the Indianapolis 500?

1 answer:

3 0

I'm such a devoted NASCAR fan that I don't even know if the starting line and finish line at Indy are the same line ... or maybe they're in different places, like the 100-meter sprint in track.

I have no idea, but I'm going to guess that the start and finish at Indy are the SAME line.

If that's true, then the displacement of a car that runs the whole 500 miles is very close to <em>ZERO</em>.

Displacement is the distance and direction between the place where the object starts out and the place where it ends up. The route it follows to get from the start to the finish is completely ignored, and doesn't matter.

(Do they the Indianapolis 500 in "stock" cars ? ?)

How much time would it take for an airplane to reach its destination if it traveled at an average velocity of 820 km/hr NE for a

Vladimir79 [104]

Answer:

Time, t = 6.34 hours.

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

$Velocity = \frac{displacement}{time}$

Therefore, making time the subject of formula;

$Time = \frac{displacement}{velocity}$

Given the following data;

Displacement = 5200km

Average velocity = 820km/hr

Substituting into the equation, we have;

$Time = \frac{5200}{820}$

Time = 6.34 hours.

<em>Hence, it would take 6.34 hours for the airplane to reach its destination. </em>
