A ball is thrown upward from a height of 5m with an initial velocity of v,- = 9.8m/s. (l)Calculate the maximum height the ball will reach. (2)Calculate the total time from the hall's launch to its hitting the ground. Solution: The initial position of the ball is y.- = 5m. The initial velocity is v,- = 2m/s and the acceleration is a = 9.80m/32. When the ball reaches its maximum height, its
