A fireworks mortar is launched straight upward from a pool deck platform 10 m off the ground at an initial velocity of 62 m/sec. The height of the mortar can be modeled by h(t) = -4.9t^2 + 62t+10, where h(t) is the height in meters and t is the time in seconds after launch. What is the maximum height? Round to the nearest meter (do not include units in your answer).
