How this connects to AP Physics 1 (Topic 1.2, Displacement, Velocity, and Acceleration): for constant acceleration, Δx = v₀t + ½at², v = v₀ + at, and v² = v₀² + 2aΔx. Pick the equation that contains the quantity you know and the one you want. Stars drop if you need many attempts, so do the algebra first, then launch.
