Hint: Use a graphing calculator to help solve this problem.
Given: A projectile is launched upward at a velocity of 140 ft/sec on Earth. The projectile starts at an initial vertical distance of 130 feet.
Find:a)Write the function that describes the height of the projectile with respect to time.
h(t) = t2 + t +
b)At what time does the projectile reach the maximum height?[Round your answer to the nearest tenth.]
c)Determine the maximum height of the projectile.[Round the answer to the nearest foot.]
d)At what time does the projectile reach ground level?[Round your answer to the nearest tenth.]
