What would be the equation for the Horizontal Velocity with a given theta (∅)?

• Vx = Vix x cos ∅

• Vy = Viy x sin ∅

• Vx = Viy x tan ∅

• Vx + Viy = Vi x tan ∅

What would be the equation for the Vertical Velocity with a given theta (∅)?

• Vx = Vix x cos ∅

• Vy = Viy x sin ∅

• Vx = Viy x tan ∅

• Vx + Viy = Vi x tan ∅

Given the following:

Vix = 23 m/s

∅ = 20 degrees

Given the following:

Viy = 125m/s

∅ = 13 degrees
