SUMMARY

The initial vertical velocity (Voy) in projectile motion is calculated using the formula Voy = Vo * sin(θ), where Vo represents the total initial velocity and θ is the angle of projection. For an object with an initial velocity of 50 m/s at an angle of 30 degrees, the calculated vertical initial velocity is approximately 24.99 m/s. This calculation is derived from the trigonometric relationship in a right-angled triangle formed by the initial velocity and its horizontal and vertical components.

I used to be really good at measuring stuff and all in projectile.But after a while i forgot how to measure the Voy(initial vertical velocity)
si it like Voy=Vo sin(0[angle sign])
but how does an object with an initial velocity of 50 m/s and an angle of 30 degrees have an Voy (or Vy) of 24.99?

Firstly, you are not measuring the initial vertical velocity; you are calculating it from the angle of projection and the total inital velocity.

Yes, the vertical initial velocity is given by V0sin(theta)-- you can see this by drawing a diagram: the initial velocity and its horizontal and vertical components form a right angled triangle. Use trigonometry on this triangle.
