We have a ball thrown vertically upward with an initial velocity of 49 meters per second. We need to find the maximum height it reaches and the total time for it to return to the ground. The graph shows the trajectory of the ball over time, reaching a maximum height of 122.5 meters at 5 seconds, and returning to the ground after 10 seconds.
