Which one of the following formulas would you need to use to calculate acceleration, if you are given the change in velocity and a time interval?

• v = Δx / Δt

• Δx = x _f - x _i

• a = Δv / Δt

• Δt = t _f - t _i

Which one of the following formulas would you need to use to calculate displacement, if you are given the initial and final position of an object?

• v = Δx / Δt

• Δx = x _f - x _i

• a = Δv / Δt

• Δt = t _f - t _i
