Most hummingbirds can fly with speeds of nearly 50.0 km/h. Suppose a hummingbird flying with a velocity of 50.0 km/h in the forward direction accelerates uniformly at 9.20 m/s^2 in the backward direction until it comes to a hovering stop. What is the hummingbird's displacement?

  • physics -

    Initial velocity, u = 50 km/h = 13.89 m/s
    Final velocity, v = 0 km/h = 0 m/s
    Acceleration, a = -9.2 m/s
    Displacement, S
    2aS = v²-u²
    S=(v²-u²)/(2a)

    Can you do the rest?
