Projectile motions problems are some of the most important problems you will encounter in this course. Through this discussion, we will solve a projectile motion problem step by step
Assume a projectile is launched from ground height over a flat plane, at an angle of 50 degrees above the horizontal with an initial speed of 100m/s.
What is the initial velocity of the projectile parallel to the ground (in the x-direction) and perpendicular to the ground (in the y-direction)?
