Projectile Motion: Finding Initial Velocity

[cookie76]

Hello,

When trying to find initial velocity in Proyectile motion can I use the formula or Range: R=Vo^2 x sin angle / Gravity

The question is if the velocity I get through that equation will be the vector in X, Y or the resultant one?

Thanks

Hello, can you please help me with my question about the range,

thanks

Welcome to PF

Vo refers to the resultant velocity.

By the way, the range formula is not quite correct as written:

R=Vo^2 x sin angle / Gravity
