Suppose you throw a ball straight up from the ground with a velocity of 224224 feet per second. As the ball moves up, gravity slows it. Eventually, the ball begins to fall back to the ground. The height h of the ball after t seconds in the air is given by the equation h equals negative 16 t squared plus 224 th=−16t2+224t. Use the given information to answer parts a through c. how long will it take to reach a height of 724ft

Suppose you throw a ball straight up from the ground with a velocity of 224 feet per second. As the ball moves up, gravity slows it. Eventually, the ball begins to fall back to the ground. The height h of the ball after t seconds in the air is given by the equation h = -16t^2 + 224t. Use the given information to answer: a. Find the height of the ball after four seconds. (Type a whole number) b. How long will it take the ball to reach a height of 768 ft? c. How long after you throw the ball will it return to the ground? (Type a whole number)

Suppose you throw a ball straight up from the ground with a velocity of 256 feet per second. As the ball moves up, gravity slows it. Eventually, the ball begins to fall back to the ground. The height h of the ball after t seconds in the air is given by the equation h = -16t2 + 256t 1. Find the height of the ball after 2 seconds. 2. How high does the ball go? 3. How many seconds does it take for the ball to hit the ground?

A ball is thrown from a height of 225 feet with an initial downward velocity of 21 ft/s. The ball's height h (in feet) after t seconds is given by the following equation: h = 225 - 21t - 16t^2. How long after the ball is thrown does it hit the ground? Round answers to the nearest hundredth.
