In summary, the distance from the cannon can be maximized by adjusting the angle and velocity of the projectile launched. The angle of launch directly affects the distance, with higher angles resulting in greater distances as long as the velocity remains constant. The velocity also plays a role, with higher velocities leading to longer distances, but other factors such as air resistance and projectile weight and shape can also impact the distance. Determining the optimal angle and velocity for maximizing distance will depend on different factors and may require experimentation and calculations.

The correct answer is theta = 70.5 degrees. I'd like to know if I'm on the right track. Do I simply solve for theta? Is there a better approach that circumvents all of this messy algebra? Much appreciated!

You do not need to solve the quadratic. If r is always increasing the quadratic has no solutions. What condition on the parameters leads to that?
 

1. How is the distance from the cannon maximized?

The distance from the cannon is maximized by adjusting the angle and velocity of the projectile launched from the cannon.

2. What is the relationship between the angle and distance from the cannon?

The angle of launch has a direct impact on the distance from the cannon. The higher the angle, the greater the distance, as long as the velocity remains constant.

3. How does the velocity affect the distance from the cannon?

The greater the velocity of the projectile, the farther it will travel from the cannon. However, at very high velocities, air resistance and other factors may come into play and affect the distance.

4. What factors, other than angle and velocity, can affect the distance from the cannon?

Air resistance, wind speed and direction, and the weight and shape of the projectile can also impact the distance from the cannon.

5. Is there an optimal angle and velocity for maximizing the distance from the cannon?

The optimal angle and velocity for maximizing distance from the cannon will depend on various factors such as the specific cannon and projectile being used, as well as environmental conditions. Experimentation and calculations can help determine the most effective combination.
