What is the formula for displacement?

• s = v · t

• Δx = x_f - x_i

• s = 1/2 a t^2

• s = v_i + v_f

What is the formula for average velocity?

• v_avg = d/t

• v_avg = Δx/Δt

• v_avg = (v_i + v_f)/2

• Both A and B

What is the formula for instantaneous velocity?

• v = d/t

• v = lim(Δt → 0) (Δx/Δt)

• v = (v_i + v_f)/2

• v = d/t^2

What is the formula for average acceleration?

• a_avg = Δv/Δt

• a_avg = (v_f - v_i)/t

• Both A and B

• a_avg = F/m
