Calculate the initial velocity components using "Vy(0)" and "Vx(0)." Imagine, for example, a helicopter drops a package downward from the top of a 25-story building at an angle 30 degrees from vertical, with a velocity of 500 meters per second. Then Vy(0) = 500 x sin (-60) = -250√3 m/s and Vx(0) = 500 x cos (-60) = 250 m/s.
Calculate the time (t) of impact. Use the initial and final coordinates as well as the velocity value. Imagine the helicopter is 50 m above ground level.
Choose (0,0) as the original coordinates. When computing, y(t)=y(0)+Vy(0)t-0.5gt^2 becomes -50=-250√3t-4.90t^2.
Calculate with the equation 2a(y(t)-y(0))=Vy(t)^2-Vy(0)^2 to solve for the vertical impact load.
Compute the vertical impact loads utilizing the Pythagorean theorem to sum the final velocity, V(t)^2 = Vx(t)^2 + Vy(t)^2.
The package accelerated in its descent, because gravity pulled it down.
