- 9. Multiple ChoiceA soccer ball is kicked from the ground with an initial upward velocity of 90 feet per second. The equation h=-16t2 + 90t gives the height h of the ball after t seconds.
What is the maximum height of the ball?126.56 ft5.625 sec2.81 sec90 ft - 10. Multiple ChoiceAn object in launched directly upward at 64 feet per second (ft/s) from a platform 80 feet high. Its height is represented by the equation
s(t) = –16t2 + 64t + 80.
What will be the object's maximum height?2 ft80 ft144 ft64 ft - 11. Multiple ChoiceIf a toy rocket is launched vertically upward from ground level with an initial velocity of 128 feet per second, then its height h after t seconds is given by the equation
h(t) = -16t2 +128t
When will the object reach its maximum height?4 ft0 seconds0 ft4 seconds - 12. Multiple Choice
A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function
h = -16t2 + 64t + 960.
How many seconds did it take for the ball to reach its maximum height?10 seconds64 seconds960 seconds2 seconds - 13. Multiple ChoiceAlain throws a stone off a bridge into a river below. The stone's height (in meters above the water), x seconds after Alain threw it, is modeled by:
