projectile with drag part 1
What is the equation of motion of a particle that has a drag force acting on it? It's important to note that we've assumed that the drag force is proportional to the velocity at all times. In reality, other factors are involved too like...

Using the R Position Vector to find Velocity and Acceleration
Unit vectors and the derivative are used to determine the velocity and acceleration of an object from the object’s r position vector. The motion is identified as Uniformly Accelerated Motion.

Understanding the Range Equation of Projectile Motion
The Horizontal Range of a Projectile is defined as the horizontal displacement of a projectile when the displacement of the projectile in the y-direction is zero. This video explains how to use the equation, why a launch angle of 45°...

Introduction to Projectile Motion
My strategy for solving any projectile motion problem. You need to split the variables in to the x and y directions and solve for time. Sounds simple and it really is, usually.
