Which kinematic formula would be most useful to solve for the target unknown? Choose 1 answer: A v = v0 + at B ?x = ((v + v0)/2)t C ?x = v0t + 1/2at^2 D v^2 = v0^2 + 2a?x E ?x = vt - 1/2at^2

          Which kinematic formula would be most useful to solve for the target unknown?

Choose 1 answer:

A v = v0 + at

B ?x = ((v + v0)/2)t

C ?x = v0t + 1/2at^2

D v^2 = v0^2 + 2a?x

E ?x = vt - 1/2at^2

Step 1

Given: Initial velocity (V₀) = 20 km/h 1 km/h = 0.27778 m/s V₀ = 20 km/h * 0.27778 m/s = 5.5556 m/s ** Show more…

A passenger plane is traveling down the runway with a speed of 20 km/h, then speeds up with constant acceleration over 2.4 km. After accelerating for 59 s, the plane takes off. We want to find the final velocity of the plane at the moment of take-off. Which kinematic formula would be most useful to solve for the target unknown? Choose 1 answer: v = v0 + at Δx = ((v + v0)/2)t Δx = v0t + 1/2at^2 v^2 = v0^2 + 2aΔx Δx = vt - 1/2at^2
