equations for projectiles ( type 1, 2, & 3)

Type 1 time formula

Type 2 time formula

Type 3 time formula

for all projectiles, a_x= ?

= 0

for all projectiles, a_y = ?

= -g

Type 1: V_ox= ?

= V_o

Type 1: V_oy= ?

= 0

for all projectiles: Δx= ?

= V_oxt

Type 2 & 3: V_ox= ?

= Cos(θ)V_o

Type 2 & 3: V_oy= ?

= Sin(θ)V_o

What should you do first with projectiles?

Solve for V_ox & V_oy … if not able to, systems of equations with the x and y equation.

Type 2: V_oy = ?

= -V_y

For type 3: When is ΔY pos (+)?

starts low, ends higher

For type 3: When is ΔY neg (-)?

starts high, ends low
