Chapter 3B 2 Motion in Two Dimensions time = t i position = r i time = t f position = r f average velocity v av = r t instantaneous velocity = v instantaneous velocity = v instantaneous velocity = v instantaneous velocity = v
Chapter 3B 3 Vector Components Displacement, velocity, and acceleration vectors can separated into their x and y components: r = ∆ x + y v = v x + v y a = a x + a y x = ∆ r cos θ v x = v cos a x = a cos y = ∆ r sin v y = v sin a y = a sin

4 Equations of Motion Our equations of motion can be applied to the x and y components independently: 2D motion problems can be treated as two separate 1D motion problems. Time is the quantity that relates them. v x = v 0 x + a x t x = 1 2 v 0 x + v x ( 29 t x = v 0 x t + 1 2 a x t 2 x = v x t - 1 2 a x t 2 v x 2 = v 0 x 2 + 2 a x x v y = v 0 y + a y
