A ball is kicked from the ground at point 0 with an initial velocity vọ = 20 m/s that makes an angle 0 = 30° with the horizontal. This ball reaches its maximum height at point A and then returns to the ground at point B as shown in the figure. (g = 10m/s²) The time taken by the ball to reach the maximum height at point A (toa) is equal to:
