Finding Horizontal & Vertical Components (parts)

Initial Horizontal
Component of Velocity

 Vix = VcosӨ (on reference table)

Initial Vertical
component of velocity

 Viy = VsinӨ (on reference table)

 Ex) Which angle of projection causes a projectile to stay in the air longer?   50 or 70 degrees?

70 degrees,

(closest to 90,
longer time in air)
