200M An object projected upwards with a velocity of 80 feet per second from a height of 20 feet above the ground is modelled by the function h(t)=-16t2 + 80t+20. A. [3 pts] How many seconds after launch will the object reach its maximum height? Round your answer to one decimal place. B. [3 pts] Find the maximum height that the object reaches. Round your answer to one decimal place. C. [3 pts] Find the x-intercept and explain its meaning on the context of the problem. 200M An object projected upwards with a velocity of 80 feet per second from a height of 20 feet above the ground is modelled by the function h(t)=-16t2 + 80t+20.
