In summary, the conversation discusses various formulas and equations for solving projectile motion problems, including calculating initial velocity, finding the range, and accounting for air resistance. The equations for solving these problems in one or two lines involve factors such as initial position, time, acceleration due to gravity, and mass of the object. Additionally, to take air resistance into account, the formula v = v<sub>0</sub>*e<sup>-kt/m</sup> can be used.

This is a nice approach. It does seem to have some advantages over the standard approach.

1. What is projectile motion?

Projectile motion is the motion of an object through the air or space under the influence of gravity, with no other forces acting on it.

2. How do I solve projectile motion problems in one or two lines?

To solve projectile motion problems in one or two lines, you can use the equations of motion: x = x0 + v0t + 1/2at^2 and v = v0 + at, where x is the final position, x0 is the initial position, v0 is the initial velocity, a is the acceleration, and t is the time.

3. What are the key factors to consider when solving projectile motion problems?

The key factors to consider when solving projectile motion problems are the initial velocity, angle of launch, and acceleration due to gravity.

4. Can I use the same equations to solve projectile motion problems in both one and two dimensions?

Yes, the same equations can be used to solve projectile motion problems in both one and two dimensions. However, in two dimensions, you will need to break down the motion into horizontal and vertical components.

5. What are some common mistakes to avoid when solving projectile motion problems?

Some common mistakes to avoid when solving projectile motion problems are forgetting to account for the acceleration due to gravity, using the wrong units, and not considering the direction of the velocity and acceleration vectors.
