Approximately, when will the object hit the ground? 85.00 seconds 69.00 seconds 0.33 seconds 2.30 seconds ***A ball is thrown into the air with an upward velocity of 28 ft/s. Its height (h) in feet after t seconds is given by the function h= -16t^2 + 28t + 7. How long does it take the ball to reach its maximum height? What is the ball’s maximum height? Round to the nearest hundredth, if necessary. Reaches a maximum height of 7 feet after 1.75 seconds. ***Reaches a maximum height of 43.75 feet after 0.88 seconds. Reaches a maximum height of 17.5 feet after 0.88 seconds. Reaches a maximum height of 19.25 feet after 0.88 seconds. A catapult launches a boulder with an upward velocity of 148 ft/s. The height of the boulder (h) in feet after t seconds is given by the function h= -16t^2 + 148t + 30. How long does it take the boulder to reach its maximum height? What is the boulder’s maximum height? Round to the nearest hundredth, if necessary. Reaches a maximum height of 30 feet after 9.25 second. Reaches a maximum height of 640.5 feet after 4.63 seconds. Reaches a maximum height of 1,056.75 feet after 4.63 seconds. ***Reaches a maximum height of 372.25 feet after 4.63 seconds.
