A ball is thrown horizontally from the roof of a building 58.5 m tall and lands 38.7 m from the base. What was the ball's initial speed in m/s?
Hint: Find the horizontal velocity by calculating the time of flight and using the horizontal distance.

  • Physics(urgent) - ,

    how long was it in the aIr?

    h(f)=h(o)+vv*time - 4.9 t^2
    solve for t.

    now in the horizontal, you have the time, the distance, solve for the initial velocity
