Velocity and height of an arrow

In summary, the conversation and attempts at a solution involve calculating velocity using the given values of k, m, d, and g. A shortcut formula for finding velocity is also mentioned. The final calculated velocity is 65.3m/s.

This is great because I was just having trouble calculating velocity tonight and finally figured it out.

You've got the height right and a short cut I discovered to finding velocity is
that velocity equals the square root of 2xgxh

v=[tex]\sqrt{}2gh[/tex] so v=[tex]\sqrt{}2x9.8x217.55[/tex]

v=65.3m/s
 

1. What is the relationship between velocity and height of an arrow?

The velocity and height of an arrow are directly related. This means that as the velocity of the arrow increases, the height it can reach also increases. Similarly, as the velocity decreases, the height will also decrease.

2. How does the weight of the arrow affect its velocity and height?

The weight of the arrow does have an impact on its velocity and height. A heavier arrow will require more force to be propelled, resulting in a lower velocity and height. On the other hand, a lighter arrow will require less force and can achieve a higher velocity and height.

3. What factors besides velocity and weight can affect the height of an arrow?

The height of an arrow can also be affected by factors such as air resistance, wind speed and direction, and the angle at which the arrow is released. These factors can either increase or decrease the height the arrow can reach.

4. Is there a maximum height an arrow can reach?

Yes, there is a maximum height an arrow can reach. This is determined by the initial velocity of the arrow, as well as the angle at which it is released. Once the arrow is released, it will continue to rise until the force of gravity overcomes its upward motion, causing it to fall back to the ground.

5. How can the velocity and height of an arrow be measured?

The velocity and height of an arrow can be measured using various methods such as using a chronograph to measure its speed, and using a rangefinder to determine the height it reaches. Additionally, mathematical equations can also be used to calculate these values based on known factors such as the angle of release and initial velocity.
