A baseball is thrown into the air from a height of 5 feet. The ball reaches a maximum height of 43.5 feet and spends a total of 3.2 seconds in the air. Which equation models the height of the baseball? Assume that acceleration due to gravity is –
16 ft/s2
H(t)=16t^2+49.6t+5
H(t)=-16t^2+5t+49.64
H(t)=-16t^2+49.64t+5
H(t)= 16t^2+ 5t+49.64
